Find the missing letters.
DGJ, FIL, (?), GLQ, INS, KPU.
There are two series DGJ, FIL, HKN and GLQ, INS, KPU. The first letter in every group of the series comes after a gap of one letter, i.e., D, F, H, and the second and third letters of each group have the same sequence, i.e., GIK and JLN. Same is the case with the second series.
A boat can cover 120 km in downstream in 12 hours and 100 km in upstream in 10 hours. Find the distance travelled by the boat in still water in 5 hours.
A man can swim at the rate of 8 km/hr in still water. If the speed of the water is 3 km/hr, then the time taken by him to swim 15 km upstream is
