CAT 2017 Set-1 | Question: 73
A man travels by a motor boat down a river to his office and back. With the speed of the river unchanged, if he doubles the speed of his motor boat, then his total travel time gets reduced by $75\%$. The ratio of the original speed of the motor boat to the speed of the river is $\sqrt{6}/\sqrt{2}$ $\sqrt{7}/2$ $2\sqrt{5}/3$ $3:2$

CAT 2001 | Question: 20
At his usual rowing rate, Rahul can travel $12$ miles downstream in a certain river in six hours less than it takes him to travel the same distance upstream. But if he could double his usual rowing rate for this $24$ miles round trip, the downstream $12$ miles would then take only one ... the current in miles per hour? $\frac{7}{3}$ $\frac{4}{3}$ $\frac{5}{3}$ $\frac{8}{3}$
