Ravina can do the same work in 12 days while Gitika can do it in 32 days. All of them started to work together but Rashmi leaves after 4 days. Ravina leaves the job 3 days before the completion of the work. How long the work last?​

Answer 1

Answer:

Let the work lasted for N days,

Then, Rashmi's 4 day's work + Ravina (N - 3) day's + Gitika's N day's work = 1

⇒ (4/16) + (N - 3) / (124/5) + N/32 = 1

⇒ 5(N - 3)/64 + N/32 = 1 - 1/4

⇒ [5(N - 3) + 2N] / 64 = 3/4

⇒ 7N - 15 = 48

∴ N= (48 + 15)/7 = 63/7 = 9 days
