Question

1. Minti can do a piece of work in 12 days. Minti and Rinki together can finish the work in 8 days.
Find: (a) the number of days in which Rinki alone can finish the work.
(b) the work left if Rinki alone works on it for 4 days.​

Answer 1

Step-by-step explanation:

Wok done by Minti in 8 days = 8/12 = 2/3

Work done by Rinki in 8 days = 1/3

1/3 wirk done by Rinki in 8 days

1 work done by Rinki in 24 days

Work left after Rinki alone works for 4 days

= 1 – 1/6 = 5/6
