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.

Let x be the number and y be the quotient.

x = 56*y + 29.

x = (8*7*y) + ((8*3) +5).

x = 8(7y+3) + 5.

So if the number is divided by 8, we get the remainder as 5.

No = x, y= Quotient.

x = 56y + 29.

Here 29=remainder.

Now divide whole by 8.

As its given dividing the same No. by 8.

x/8 = 56y/8 + 29/8.

And

8)29(3
24
-----
5
-----
So answer is 5.

Let the number be 'x'.

On dividing 56,

We got the quotient plus 29 remainder.

So, the number 56x+29.

Now let's divide this number by 8.

56x is completely divisible by 8, so remainder zero.

On dividing 29 gives remainder of 5.

That's the answer.

56+29=85

therefore 85/8--->Remainder is 5

The remainder,when (35)^128 is divided by 50 is
1)35 2)25 3)5 4)45

(divisor*quotient)+remainder=dividend
so that 56k+29=X
therefore 8(7k+24)+5=X
so that the remainder is 5 .

x = 56*y + 29

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

The remainder is 5

Shortest answer has given by Ramesh.

The remainder rule: consider r=29
smaller divisor d=8
if r>d then rem=rem of r/d
here 29/8=5 rem
hence rem=5

1.Mutiply 56*29=1624.
2.Add 1624+29(R)=1653.
3.now to check that divide 56)1653(
.....
29
4.the same no u divide by 8 you will get remainder 5.
5.so the no is 1653.
That's it so very simple...!!!
