What least number must be subtracted from 3401, so that the number is completely divisible by 11?1). 32). 13). 24). 0

Answer»

For this to be divisible by 11, sum of numbers at even places - sum of numbers at odd places MUST be zero or divisible by 11

⇒ (4 + 1) - (3 + 0) = 5 - 3 = 2

instead of 2 there must be 0, so that it will be divisible by 11

∴ 2 must be subtracted from the number to MAKE it divisible by 11
