Aptitude - Square Root and Cube Root - Discussion

@Vinitha & @Abhinav.

First, you have to understand the problem and convert the paise into a square root.

If question demands we have to convert it into paise.

So, in such kinds of sums, do we always have to convert 1 to paise?

How it would be if a remainder is a 2 digit of first division? For eg : sqrt(7921) would be 89 how?

As the question says, that the amount in paise being collected from every member = The number of members.

Suppose if there is 1 guy then he will contribute on 1 paise.

Similarly 5 members will contribute 5 paise each. Which means the total amount collected will be 5x5 = 25.

Therefore here also 5929 = mxm.

Please @Krishna Garu. Can give one more example please?

What will happen if the number is 15625?

Why it has 100 in solution but no 100 in situation ?

@Gunjan Rana.

7|59 29 |7
   |49 |
 ---------
   147 |10 29 |7
          |10 29 |
           ---------
           00 00

First of all we should divide the given number into two equal pieces it is 5929 so that 59 and 29 are the two pieces.

Now we have to divide the first part with the squares only.
now 10 is remainder.

After that we have to take the second part of the number that is 29.
now the value is 1029.

Previously we took 7 to divide the first now we should take the double of the 7 that is 14.
if the number can divide with 147*7=1029.
remainder is zero.

If it can able to divide 146 then you should multiply with 6. that is 146*6.

Similarly 145*5.
144*4.
143*3.

The last position should be match.

Another example for you.
1|1 69 |1
   |1 |
 ---------
   23 |0 69 |3
       |0 69 |
         ---------
           00 00

13 is your answer.

Can any body can explain how to find square root of digit 5929 ?
