A conveyer belt delivers baggage at the rate of 3 tons in 5 minutes, and a second conveyer belt delivers baggage at the rate of 1 ton in 2 minutes. How much time will it take to get 33 tons of baggage delivered using both the conveyer belts ?

First belt delivers 3 tons in 5 minutes, so its rate is 3/5 = 0.6 tons per minute. Second belt delivers 1 ton in 2 minutes, so its rate is 1/2 = 0.5 tons per minute. Combined rate = 0.6 + 0.5 = 1.1 tons per minute. Time required to deliver 33 tons = 33 ÷ 1.1 = 30 minutes. Therefore the total time using both conveyor belts together is 30 minutes, which corresponds to option 2.
