A) 18
B) 42
C) 60
D) 42 or 60
Correct Answer: D
Solution :
[d] If \[3q+9=18\,\,\,\,\Rightarrow \,\,\,\,\,q=3\] So the three numbers are 3, 5 and 9. This is not true as 9 is not a prime number. But if 3q+ 9 = 42 or 60, we have q = 11 or 17. In this case, the numbers are 11, 13, 17 or 17, 19, 23 which is true.You need to login to perform this action.
