Question
A and B can complete a work together in 24 days. If A
alone can complete one-fourth of the work in ‘x’ days and remaining work is completed by B alone in 3x days, then find the value of x.Solution
Time taken by A to complete the work = (x × 4) = 4x days Time taken by B to complete the work = (3x × 4/3) = 4x days According to question, => (1/4x) + (1/4x) = 1/24 => (1 + 1)/4x = 1/24 => 4x = 48 => x = 12
