Question
If a group of 8 boys and 12 girls can complete a task in 40
days, and a team of 4 girls alone can finish the same task in 80 days, how long will it take for 32 boys to finish the entire task on their own?Solution
ATQ;
Task done by 4 girls in 1 day = 1/80
Task done by 12 girls in 1 day = 3/80 = 1/26.67
Task done by 8 boys = 1/40 – 1/26.67 = 1/120
Task done by 32 boys = 4/120 = 1/30
Hence, required time = 30 days
