7) If 1023 and 1078 both divisible by then 1023+1078 also divisible by O 11,13 O 11,21 O 13,13 11,11 O OOptionCorrect option is

B

2

⇒ When 1056÷23, we get 21 as a remainder.

⇒ So, 23−21=2 must be added to 1056 in order to sum completely divisible by 23.

∴ 1056+2=1058

∴ The least number should be added to 1056, so that the sum is completely divisible by 23 is 2.
