Question
A is thrice as efficient as B and can finish a piece of
work in 32 days less than B. B can finish this work in how many days?Solution
Ratio of efficiency of A and B = 3: 1
A will take 1/3 of time as compared to B.
Say, B takes 3x days and A takes x days.
∴ 3x – x = 32 ⇒ x = 16
∴ B takes 16 × 3 = 48 days to do the work.
