Question

What least number must be subtracted from 21359 such that the remainder is divisible by 124?
1. 62
2. 28
3. 31
4. 56

Answer 1

Correct Answer - Option 3 : 31

Given:

Dividend = 21359 

Divisor = 124

Formula Used:

Dividend = divisor × Quotient + Remainder

Calculation:

To get the least number divide 21359 by 124

⇒ 21359 ÷ 124 = 172 + 31

⇒ Quotient = 172 

⇒ Remainder = 31 

⇒ 21359 - 31 = 21328 

⇒ 21328 is completely exactly divisble by 124

∴ The least number to be subtracted is 31
