Correct Answer - Option 4 : 149
Calculation:
The smallest number divisible by 12, 16 and 18 = LCM of 12,16 and 18
⇒ LCM of 12, 16 and 18 = 144
As we need remainder 5 in each case so the number = LCM + 5
⇒ 144 + 5 = 149
∴ The smallest number which when divided by 12,16 and 18 gives remainder 5 is 149.
