Question
A and B can complete a work together in 36 days. If A
alone can complete one-third of the work in lsquo;xrsquo; days and remaining work is completed by B alone in 2x days, then find the value of x.Solution
Time taken by A to complete the work = (x ×  3) = 3x days Time taken by B to complete the work = (2x ×  3/2) = 3x days According to question, => (1/3x) + (1/3x) = 1/36 => (1 + 1)/3x = 1/36 => 3x = 72 => x = 24
