SQUARE AND CUBE ROOTS

Formula:

The Product of two same numbers in easiest way as follow.Example:let us calculate the product of 96*96Solution: Here every number must be compare with the 100.See here the given number 96 which is 4 difference with the 100.so subtract 4 from the 96 we get 92 ,then the square of thenumber 4 it is 16 place the 16 beside the 92 we get answeras 9216.

9 6- 4————–9 2————–4*4=169 2 1 6

Page 4: For Bank Po Maths

therefore square of the two numbers 96*96=9216.

Example: Calculate product for 98*98Solution: Here the number 98 is having 2 difference when compareto 100 subtract 2 from the number then we get 96 square thenumber 2 it is 4 now place beside the 96 as 9604

9 8- 2————-9 6————-2*2=49 6 0 4.so, we get the product of 98*98=9604.

Example: Calculate product for 88*88Solution: Here the number 88 is having 12 difference when compareto 100 subtract 12 from the 88 then we get 76 the square of thenumber 12 is 144 (which is three digit number but should placeonly two digit beside the 76) therefore in such case add one to6 then it becomes 77 now place 44 beside the number 77 we will get7744.88-12————76———–12*12=144

76+ 144——————–7744——————–

Example: Find the product of the numbers 46 *46?Solution:consider the number 50=100/2. Now again go comparision withthe number which gets when division with 100.here consider the number50 which is nearer to the number given. 46 when compared with thenumber 50 we get the difference of 4. Now subtract the number 4 fromthe 46, we get 42. As 50 got when 100 get divided by 2.so, divided the number by 2 after subtraction.42/2=21 now square the the number 4 i.e, 4*4=16just place the number 16 beside the number 21

Page 5: For Bank Po Maths

we get 2116.4 64—————-4 2 as 50 = 100/2

42/2=21now place 4*4=16 beside 212 1 1 6

Example: Find the product of the numbers 37*37Solution:consider the number 50=100/2now again go comparision with the number which gets whendivision with 100.here consider the number 50 which is nearer to the number given.37 when compared with the number 50 we get the difference of 13.now subtract the number 13 from the 37, we get 24.as 50 got when 100 get divided by 2.so, divided the number by 2 after subtraction.24/2=12now square the the number 13 i.e, 13*13=169just place the number 169 beside the number 21now as 169 is three digit number then add 1 to 2 we get1t as 13 then place 69 beside the 13we get 1369.

24/2=12square 13* 13=169

1 2+ 1 6 9———————–1 3 6 9————————-

Example: Find the product of 106*106Solution: now compare it with 100 ,The given number is more then 100then add the extra number to the given number.That is 106+6=112

Page 6: For Bank Po Maths

then square the number 6 that is 6*6=36just place beside the number 36 beside the 112,thenwe get 11236.1 0 6+ 6———————1 1 2——————–now 6* 6=36 place this beside the number 112, we get1 1 2 3 6

Square root: If x2=y ,we say that the square root of yis x and we write ,√y=x.

Cube root: The cube root of a given number x is the numberwhose cube is x. we denote the cube root of x by x1/3 .

Examples:

1.Evaluate 60841/2 by factorization method.

Solution: Express the given number as the product of primefactors. Now, take the product of these prime factors choosingone out of every pair of the same primes. This product gives thesquare root of the given number.

Thus resolving 6084 in the prime factors ,we get 60842 60242 30423 15213 50713 169136084=21/2 *31/2 *131/260841/2=2*3*13=78.Answer is 78.

2.what will come in place of question mark in each of the followingquestions?

i)(32.4/?)1/2 = 2ii)86.491/2 + (5+?1/2)2 =12.3

Solution: 1) (32.4/x)1/2=2Squaring on both sides we get32.4/x=4

Page 7: For Bank Po Maths

=>4x=32.4=>x=8.1

Answer is 8.1

ii)86.491/2 + √(5+x2)=12.3

solutin:86.491/2 + (5+x1/2 )=12.39.3+ √(5+x1/2 )=12.3=> √(5+x1/2 ) =12.3-9.3=> √(5+x1/2 )=3Squaring on both sides we get(5+x1/2 )=9x1/2 =9-5x1/2 =4x=2.Answer is 2.

3.√ 0.00004761 equals:

Solution: √ (4761/108)√4761/√ 108. 69/100000.0069.Answer is 0.0069

4.If √18225=135,then the value of √182.25 + √1.8225 + √ 0.018225 + √0.00018225.

Solution: √(18225/100) +√(18225/10000) +√(18225/1000000) +√(18225/100000000)=√(18225)/10 + (18225)1/2/100 +√(18225)/1000 + √(18225)/10000=135/10 + 135/100 + 135/1000 + 135/10000=13.5+1.35+0.135+0.0135=14.9985.Answer is 14.9985.

5.what should come in place of both the questionmarks in the equation (?/ 1281/2= (162)1/2/?) ?

Solution: x/ 1281/2= (162)1/2/x=>x1/2= (128*162)1/2=> x1/2= (64*2*18*9)1/2=>x2= (82*62*32)=>x2=8*6*3=>x2=144

Page 8: For Bank Po Maths

=>x=12.

6.If 0.13 / p1/2=13 then p equals

Solution: 0.13/p2=13=>p2=0.13/13=1/100p2=√(1/100)=>p=1/10therefore p=0.1Answer is 0.1

7.If 13691/2+(0.0615+x)1/2=37.25 then x is equals to:

Solution37+(0.0615+x)1/2=37.25(since 37*37=1369)=>(0.0615+x)1/2=0.25Squaring on both sides(0.0615+x)=0.0625x=0.001x=10-3.Answer is 10-3.

8.If √(x-1)(y+2)=7 x& y being positive whole numbers thenvalues of x& y are?

Solution: √(x-1)(y+2)=7Squaring on both sides we get(x-1)(y+2)=72x-1=7 and y+2=7therefore x=8 , y=5.Answer x=8 ,y=5.

Allahabad Bank Clerk Examination Solved Papers Year 2010

Directions—(Q. 1–15) Read the following passage carefully and answer the questions given below it. Certain words have been printed in bold to help you locate them while answering some of the questions.

Keshav and Yash lived in neighbouring villages. Once, a fair was held nearby and they set off from their homes hoping to do some business there. Keshav filled his sack with cheap cotton, overlaid it with a layer of fine wool, and set off for the fair. Meanwhile Yash, collected some old clothes, put a layer of sheer cotton on top and made his way to the fair. Each stopped to rest under a tree and got to talking. “I have the finest wool in my sack,” boasted Keshav Not to be outdone, Yash said, “I have cotton of the most superior quality.”

The two struck a deal. They would exchange their goods and since wool was more expensive, Yash would pay Keshav an extra rupee. But Yash had no money on him. So after agreeing to pay Keshav later, they went home, laughing at each other’s folly. It did not take them long to discover that they had been duped. The next day, Keshav landed at Yash’s house. “You cheat! Give me my rupee at least.” Yash was untroubled by Keshav’s words, “Of course. But first help me find the treasure at the bottom of this well. We can divide it.” So Keshav went into the well. But each time Yash, hauled up the bucket Keshav had filled, he said, “Oh ! No treasure here. Try again.” Keshav soon realized he was being used as free labour to clean the

well. So he gave a loud shout, “Here is the treasure! Watch out it’s heavy !” Yash was amazed that there actually was treasure in the well. As soon as he pulled up the bucket he threw away the rope so that Keshav could not come up. But, what did he find in the bucket ? Keshav covered in mud ! They began fighting again. Soon it got too dark to continue and they left for their homes.

But Keshav did not give up easily. He arrived at Yash’s house a few days later. Yash spotted him and told his wife, “I will pretend to be dead. Keshav will have to give up.” But when Keshav heard Yash’s wife wailing, he rushed out to gather the villagers. “My friend has died. Let’s take his body for cremation.” Yash’s wife got scared, “Go away. I shall arrange for cremation myself !” But the villagers thought she was too grief stricken. Once they reached the cremation ground, Keshav told the villagers, “It is getting dark. I shall watch over him during the night.” When the villagers had left, Keshav said to Yash, “Stop pretending. Give me my money !” Now, a gang of thieves came upon them and seeing one figure seated on the funeral pyre and another standing next to him talking, they assumed them to be ghosts and dropped their bag of stolen goods and left at top speed. The two, saw the bag full of gold and silver ornaments and divided it between themselves. Keshav made sure he got an extra gold coin and the account was settled at last!
