Question
If a group of 20 boys and 10 girls can finish a task in
50 days, and a team of 8 girls alone can complete the same task in 120 days, how long will it take for 80 boys to finish the entire task on their own?Solution
ATQ;
Task done by 8 girls in 1 day = 1/120
Task done by 10 girls in 1 day = 10/120 = 1/12
Task done by 20 boys = 1/50 – 1/12 = 1/60
Task done by 80 boys = 4/60 = 1/15
Hence, required time = 15 days
