Question

A and B can complete a work together in 32 days. If A alone can complete one-fourth of the work in ‘x’ days and remaining work is completed by B alone in 6x days, then find the value of x.

A 24 Correct Answer Incorrect Answer
B 18 Correct Answer Incorrect Answer
C 20 Correct Answer Incorrect Answer
D 12 Correct Answer Incorrect Answer

Solution

Time taken by A to complete the work = (x × 4) = 4x days Time taken by B to complete the work = (6x × 4/3) = 8x days According to question, => (1/4x) + (1/8x) = 1/32 => (2 + 1)/8x = 1/32 => 8x = 96 => x = 12
