On dividing a number by 56, we get 29 as remainder. On dividing the same number by 8, what will be the remainder ?
4
5
6
7
Answer: Option
Explanation:

Formula: (Divisor*Quotient) + Remainder = Dividend.

Soln:

(56*Q)+29 = D -------(1)

D%8 = R -------------(2)

From equation(2),

((56*Q)+29)%8 = R.

=> Assume Q = 1.

=> (56+29)%8 = R.

=> 85%8 = R

=> 5 = R.

You take a number like 5853 which is divisible by 56 and remainder is 29 after that this no. Divided by 8 and answer. Is 5.

Let the number be X
acording to ? by / X by 56 remainder is 29
this means that x velue is =56*29=85 (remember in ? two numers substraction is not given, 85/56=1 and remainder is 29)
85/8= remainder is 5
this is the simple explanation

Assume that the num is 56+29=85.
Now divide, 85/8.
Remainder is 5.

Ramesh and Sachin are absolutely right..

Dividing number by 56, we get 29 as remainder means,
Original number we divide by 56 is = 56+29 = 85
So, When dividing 85 by 17, we get remainder 5.

Assume the number as x and the quotient is k.

Given that if the number is divided by 56 we get 29 as remainder.

X = (56*k)+29.

= 56k+24+5.

= 8(7k+3)+5.

Therefore if the number is divided by 8 we will get 5 as remainder.

Simply to assume a number, add 29 into 56 we will get 85, now devide 85 by 8 remainder will be 5.

If the 2nd divisor is a factor of 1st divisor, then divide the 1st remainder by the 2nd divisor. This is the correct answer.

The most simple way to solve these "n"type question is to put the value.

Like in this example. :suppose that the no. is 85. When we divide it by 56, the remainder is 29, as in this que. , now divide 85 by 8, we find 5 as a remainder.

So we can do this type of que. in just some seconds. And no need of paper or pen.

Let the Number= X

X= 56Q+29 ( from Dividend= Divisor * Quotient + Remainder)

here Q will be Natural number. but here for convenient we consider Q=1

So, X= 56+29= 85.

Now from 85/ 8. we get 10 as Quotient and 5 as Remainder.
