Krishna read 1/3 of a book in 1 hour. Then how much he will read in 3 1/3 hrs?
Correct option is (A) 10/9 \(\because\) Krishna read in 1 hour = \(\frac{1}{3}\) part of a book \(\therefore\) Krishna read in \(3\frac{1}{3}\) hours = \(3\frac{1}{3}\) \(\times\) \(\frac{1}{3}\) part of that book = \(\frac{3\times3+1}{3}\) \(\times\) \(\frac{1}{3}\) = \(\frac{10}{3}\) \(\times\) \(\frac{1}{3}\) = \(\frac{10}9\) part of the book.

If A pump can take 5 hrs to fill a 50 l of tank then how much time to take to fill a 75 liters of tank for the same pump?
Correct option is (D) \(7\,\frac{1}{2}\) hrs \(\because\) Time taken to fill a \(50\,l\) of tank = 5 hours \(\therefore\) Time taken to fill a \(75\,l\) of tank \(=\frac5{50}\times75\;hours\) \(=\frac{75}{10}\;hours\) = 7.5 hours = 7 hours + \(\frac12\) hours = \(7\frac12\) hours

A train travels 2 1/2 hrs at 90 kmph to travel the same distance in 2 hours, how much speed required for the train?
Correct option is (A) \(112\frac12\,km/hrs\) Distance covered by train in \(2\frac12\) hrs = speed \(\times\) time = 90 \(\times\) \(2\frac12\) km = 90 \(\times\) \(\frac52\) km = 45 \(\times\) 5 km = 225 km \(\therefore\) Speed required to covered same distance (225 km) in 2 hours \(=\frac{Distance}{Time}\) \(=\frac{225}2\,km/hrs\) \(=112\frac{1}2\,km/hrs\)
