The ratio of three numbers is respectively. If the sum of the number is 68, what is the value of of the first number?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4.
Let the three numbers be x/4, 5x/6, and x/3
Given,
x/4 + 5x/6 + x/3 = 68
⇒ (3x + 10x + 4x)/12 = 68
⇒ 17x/12 = 68
⇒ x = 48
Thus, the first number = 48/4 = 12
Thus, 1/3 of this number = (1/3) × 12 = 4
