Let, the speeds of boat A and boat B, in still water and the speed of the current be 7x kmhr, 5x kmhr and 2x kmhr, respectively. According to the question, 4D 107x 2x D 605x 2x Or, 12D 30 9D 540 Or, 3D 570 Or, D 190

the speed of boat ‘B’ in still water and the speed of the current is 7:5:2, respectively. If the time taken by boat ‘A’ to travel (4D – 10) km downstream is equal to the time taken by boat ‘B’ to travel (D + 60) km upstream, then find the value of ‘D’.

A 190

B 150

C 130

D 140
