What least number must be added to 213, so that the sum is completely divisible by 9?1). 32). 23). 14). 4

Answer»

For this to be divisible by 9, SUM of numbers at DIFFERENT places MUST be divisible by 9

⇒ Sum = 2 + 1 + 3 = 6

instead of 6 there must be 9, so that it will be divisible by 9

∴ 3 must be added from the number to make it divisible by 9
