Ram can solve 84 questions in one-hour 30 minutes. Mohan can solve 110 questions in 2 hours 30 minutes. How many questions can they solve together in two hours 30 minutes?

Ram can solve 84 questions in one-hour 30 minutes. Mohan can solve 110 questions in 2 hours 30 minutes. How many questions can they solve together in two hours 30 minutes? Correct Answer 250

Calculation:

⇒ The number of questions Ram can solve in one hour = (60/90) × 84 = 56

⇒ The number of questions Mohan can solve in one hour = (60/150) × 110 = 44

⇒ Ram and Mohan together can solve questions in one hours = 56 + 44 = 100

⇒ Both together can solve the question in 2 hours 30 minutes = 100 × (5/2) = 250

∴ The required result will be 250.

In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Pipe A takes thrice the time taken by Pipe B to fill a tank. Together they can fill the tank in 15 hours, tank A and B is opened together for 4 hours and then Pipe A is closed and after 2 more hours Pipe B is closed and an outlet Pipe C is opened which when working alone can empty the tank in 10 hours. Calculate the time taken by C to empty the tank. Quantity B: A pipe A can fill the tank in 10 hours another pipe B can fill the tank in 15 hours and with the help of third pipe C they can fill the tank in 5 hours. Pipe A is opened for 4 hours then it is closed, pipe B is closed 3 hours before filling of tank and tank C is opened the whole time. Calculate the time taken to fill the tank
