Question

kunal can paint ahouse in 15 days and hemanth can do it in 10 days.how long would they take to paint the house if they work together

Answer 1

Answer:

They would take 5 days to complete the house.

Answer 2

Answer:

6 days

Step-by-step explanation:

Time taken by Kunal to paint the house = 15 days

Work done by Kunal in 1 day = 1/15 part

Time taken by Hemanth to paint the house = 10 days

Work done by Hemanth in one day = 1/10 part

Work done by Hemanth and Kunal together in 1 day = 1/15 + 1/10

                                                                                       = (2 + 3)/30 = 5/30 = 1/6

Time taken to finish 1/6 part of work by Hemanth and Kunal = 1/1/6 days = 6  days
