Question : If the product of three consecutive numbers is 210, then the sum of the 2 smaller numbers is:
Option 1: 3
Option 2: 4
Option 3: 5
Option 4: 11
Correct Answer: 11
Solution : Given: Product of three consecutive numbers = 210 Prime factors of 210 = 2 × 3 × 5 × 7 = 5 × 6 × 7 So, 5, 6 and 7 are the three consecutive numbers. Sum of the smaller 2 numbers = 5 + 6 = 11 Hence, the correct answer is 11.
