27.
On dividing a number by 56, we get 29 as remainder. On dividing the same number by 8, what will be the remainder ?
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.

If devisor is completely divisible by new divisor then, we shuld divide the remainder.....ie
29 /8 = 5
ans 5
If not divisble answr: can'be determine
If they ask double of number simply do 29+29 =58
58 /5 = remainder is 3
29 /8 = 5
ans 5
If not divisble answr: can'be determine
If they ask double of number simply do 29+29 =58
58 /5 = remainder is 3

If divisor is completely divisible by new divisor then, we should devide the remainder.
29/8 = remainder is 5.
so, ans would be 5.
29/8 = remainder is 5.
so, ans would be 5.

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...
Then N = 56q + 29
=> N/8 = 7q + 29/8
Hence, N/8 = 7q + 3 + 5/8
Thus the remainder is 5...

Number = k*56 + 29;
Number = (k*56 + 24) + 5;
Number = 8(7k + 3) + 5;
Hence when divided by 8,rem is 5
Number = (k*56 + 24) + 5;
Number = 8(7k + 3) + 5;
Hence when divided by 8,rem is 5
