Question : The sum of three consecutive natural numbers divisible by 3 is 45. The smallest number is:
Option 1: 18
Option 2: 3
Option 3: 12
Option 4: 9
Correct Answer: 12
Solution :
Let the three consecutive numbers divisible by 3 be (x – 3), x, and (x + 3).
According to the question,
(x – 3) + x + (x + 3) = 45
⇒ 3x = 45
⇒ 3x = 45
⇒ x = $\frac{45}{3}$ = 15
So, the numbers are 12, 15 and 18.
Hence, the smallest number is 12.
