Let, the speeds of boat A and boat B, in still water and the speed of the current be 6x kmhr, 4x kmhr and 2x kmhr, respectively. According to the question, 6D 226x 2x D 704x 2x Or, 12D 44 8D 560 Or, 4D 604 Or, D 151

the speed of boat ‘B’ in still water and the speed of the current is 6:4:2, respectively. If the time taken by boat ‘A’ to travel (6D – 22) km downstream is equal to the time taken by boat ‘B’ to travel (D + 70) km upstream, then find the value of ‘D’.

A 121

B 131

C 151
