Answer 1

Answer:

A's share = ₹400

Step-by-step explanation:

Time taken to complete the work by :

• A = 12 days
• B = 15 days
• C = 20 days

So , work done by them in a day :

• A = 1/12
• B = 1/15
• C = 1/20

If all three lf them work together then the total work work by them = 1/12 + 1/15 + 1/20 = 1/5

So , days required to complete the work if the they work together = 5/1 = 5 days

Work done by A , B and C = 5/60 , 4/60 and 3/60

So , ratio of their works = 5:4:3

So , A's share = 5/12 × ₹960 = ₹400
