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.

56x+29 then if we consider x=1 we get 85 when divided by 17 we get a remainder of 0 then if we consider x=2 then we get 141 if further divided by 17 we get remainder as 5 and q=8.

This is the simplest way of all.

Since a number is divisible by 56 and gives remainder as 29.

Let the least possible number that satisfies the above condition,

So the number is = (56+29) ;

Number = 85;

(if you want just check it, 85%56 = 29).

So the same number 85%8 = 5 (as stated in the question).

As simple as that.

Given number is 56 and 56 is a multiple of 8 so every no divided.

By 56 is also divisible by 8 hence.

The remainder i.e. 29.

29/8 gives Remainder 5.

Hence 5.

This is simple question. Take any example.

56*1 = 56.

But it should leave 29 as remainder. So 56+29=85.

Let divide 85 with 8. Then get answer.(85%8=5).

Read carefully and then understand.

Let us consider that the number divisible by 56 and leaves a remainder 29 be x+29. When the same number is divided by 8 definitely the x is divisible by 8 since it is divisible 56 and 56 is divisible 8 now we should take care about 29. When 29 is divided by 8 it leaves the remainder 5.

So the answer is 5.

This is the simplest way to solve.
In less time we can get answer.

56+29 = 85.

85/8 so we get the remainder 5.

x = 56*y + 29.

= 7*8*y + 3*8 + 5.

The remainder is 5 ie (B).

When same number is divided by two different divisors such that one divisor is multiple of another divisor and the remainder R of greater is known then remainder is given by (R/d).

56 is simply divided by 8 and get 0, so whatever we multiply with it it will be divisible by 0. Now reminder value divide by 8.

29 % 8 = 5 (we get 5 as remainder).

So the answer is 5.
