If difference between total milk and total water in container B is 30 liter then find the quantity of initial mixture in container B.

A) Rs. 2550 B) Rs. 2424

12 men complete a work in 14 days. 5 days after they had started working, 3 men join them. How many more days will all of them take to complete the remaining work?

A) 5 B) 4
C) 3 D) 2
