A) 11
B) 13
C) 17
D) 19
Correct Answer: A
Solution :
Suppose that on dividing the given number by 342, we get quotient = k and remainder = 47, Then, number \[=342\text{ }k+47\] \[=(18\times 19k)+\left( 18\times 2 \right)+11\] \[=18\,(19\,k+2)+11\] So, the number when divided by 18 gives remainder 11.You need to login to perform this action.
