This made them far more compact than the first generation computers. The input for these computers were higher level languages like COBOL, FORTRAN etc.

A boy can swim a certain distance downstream in 2 hours and return in 5 hours. If the rate of stream is 3 kmph then what is the speed of boy in still wa...
A man can swim downstream in 12 minutes covering a distance of 600 meters. He takes 15 minutes to cover the same distance upstream. Find the speed of th...
A boat can cover 195 km in downstream in 10 hours and 140 km in upstream in 14 hours. Find the distance travelled by the boat in still water in 4 hours.
The speed of current is 18 km/hr. If the speed of the boat in still water had been 7 km/hr more than the original speed, then it would take 8 hours to c...
A boat takes 2 hours to travel 24 km downstream and 4 hours to travel 16 km upstream. What is the speed of the boat in still water?
The speed of a boat in still water is 12 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
A boy can swim in water with a speed of 10 km/hr in still water. If the speed of the stream is 4 km/hr, what will be the time taken by the boy to cover ...
