1.	A and B can complete a work in 5 days and 10 days respectively. They asked for the amount of ₹ 20000 for the work. But they get only 60 percent of the amount. What is the share of A after completion of the work?1. ₹ 80002. ₹ 70003. ₹ 85004. ₹ 75005. ₹ 6000
Answer» Correct Answer - Option 1 : ₹ 8000 Given: Time taken by A to complete the work = 5 days Time taken by B to complete the work = 10 days Total amount = ₹ 20000 Concept used: Time ∝ 1/efficiency Total wages = Person’s one-day work × Working days Calculation: Amount to be distributed = 20000 × (60/100) = ₹ 12000 Time taken by A = 5 days Time taken by B = 10 days ⇒ One day work of A = 1/5 ⇒ One day work of B = 1/10 ⇒ Ratio of income = 1/5 : 1/10 = 2 : 1 ⇒ Share A will get = (12000/3) × 2 ∴ A share is ₹ 8000

A and B can complete a work in 5 days and 10 days respectively. They asked for the amount of ₹ 20000 for the work. But they get only 60 percent of the amount. What is the share of A after completion of the work?1. ₹ 80002. ₹ 70003. ₹ 85004. ₹ 75005. ₹ 6000

Answer» Correct Answer - Option 1 : ₹ 8000

Given:

Time taken by A to complete the work = 5 days

Time taken by B to complete the work = 10 days

Total amount = ₹ 20000

Concept used:

Time ∝ 1/efficiency

Total wages = Person’s one-day work × Working days

Calculation:

Amount to be distributed = 20000 × (60/100) = ₹ 12000

Time taken by A = 5 days

Time taken by B = 10 days

⇒ One day work of A = 1/5

⇒ One day work of B = 1/10

⇒ Ratio of income = 1/5 : 1/10 = 2 : 1

⇒ Share A will get = (12000/3) × 2

∴ A share is ₹ 8000
