Answer : 2. "26.166 minutes"
Explanation :
Answer: B) 26.166 minutes Explanation: Upto first 5 minutes I, J and K will fill => 5[(1/20)+(1/30)+(1/40)] = 65/120 For next 6 minutes, J and K will fill => 6[(1/30)+(1/40)] = 42/120 So tank filled upto first 11 minutes = (65/120) + (42/120) = 107/120 So remaining tank = 13/120 Now at the moment filling with C and leakage @ 1/60 per minute= (1/40) - (1/70) = 3/280.So time taken to fill remaining 13/120 tank =(13/120) /(3/280) = 91/6 minutes ┬а Hence total time taken to completely fill the tank = 5 + 6 + 91/6 = 26.16 minutes.

Answer : 3. "[6 + (261/315)] days"
Explanation :
Answer: C) [6 + (261/315)] days Explanation: After day 1, A finishes 1/9 of the work. After day 2, B finishes 1/7 more of the total work. (1/9) + (1/7) is finished. After day 3, C finishes 1/5 more of total work. Total finished is 143/315. So, after day 6, total work finished is 286/315. ┬а Now remaining work =┬а 29 /315 ┬а On day 7, A will work again┬а ┬а Work will be completed on day 7 when A is working. He must finish 29/315 of total remaining work. ┬а Since he takes 9 days to finish the total task, he will need 261/315 of the day.┬а ┬а Total days required is 6 + (261/315) days.
