The sum of three numbers is 132, If the first number be twice the second and third number be one-third of the first, then the second number is?
Correct Answer: 36
Explanation:
Let second number be 3N, then, first one is 6N and the third one is 2N.
From question 3N + 6N + 2N = 132
⇒ 11N = 132
⇒ N = 12 ∴ Second number = 3N = 3 x 12 = 36
