Question
A can finish a task in 32 days, while B can complete the
same task 8 days sooner than A. If they together earn a total of Rs. 1050 for the job, how much does A receive?Solution
Time taken by ‘A’ to complete the work = 32 days Time taken by ‘B’ to complete the work = 32 – 8 = 24 days Ratio of efficiencies is inverse of number of days taken Therefore, ratio of efficiencies of ‘A’ to ‘B’ = 24:32 = 3:4 Wage received by ‘A’ = 1050 × (3/7) = Rs. 450
