Sneha alone can type a report in 14 days, while Reena can
do it in 21 days. If both work together and earn Rs. 14,700 for the job, how much will Reena get?Solution
ATQ,
Let the total work be 42 units (LCM of 14 and 21)
Efficiency of Sneha = 42/14 = 3 units/day
Efficiency of Reena = 42/21 = 2 units/day
Total efficiency = 3 + 2 = 5 units/day
Required amount that Reena will get = 14,700 × (2/5) = Rs. 5,880
