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.

Add the remainder and dividend. Here 56+29 = 85.
Divide the answer by next divisor. So 85/8.
Hence, remainder is 5.

Actually,

Number= (k*56+29).
Number= (k*56+24+5).
Number=8* (k*7+3) +5.

So divided number by 8, We get reminder 5.

The given number is divisible by 56
Then why the number may not be 56

Take k=56

56+29=85

8)85(10
80
Reminder=5

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

n = s*56+29.
n = s*56/8+24/8+5/8.

n = s*+0+0+5.
n = 56*29=1624.

1624/56 = 29 remainder.
1625/8 = 5 remainder.

Let N be the no.
Then N = 56q + 29
=> N/8 = 7q + 29/8
Hence, N/8 = 7q + 3 + 5/8
Thus the remainder is 5...

(29+x)/8 = N.

Where N is natural number and put x values are 1 2 3 4 5.

Then x least value is your answer.

56+29 = 85.

56)85(1
56

29

8)85(10
80

5

If you are not a fool you will understand.

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

Bhuvana said:   1 decade ago
Number = k*56 + 29;

Number = (k*56 + 24) + 5;

Number = 8(7k + 3) + 5;

Hence when divided by 8,rem is 5
