Question
Select the option in which the numbers are related in
the same way as are the numbers of the following sets. (43, 74, 36) (21, 58, 42) (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13-Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)Solution
The logic followed here is: (2nd number – 1st number) + 5 = 3rd number (43, 74, 36) à (74 – 43) + 5 = 31 + 5 = 36 (21, 58, 42) à (58 – 21) + 5 = 37 + 5 = 42 (71, 92, 28) à (92 – 71) + 5 = 21 + 5 = 26 → Does not follow the pattern (42, 67, 31) à (67 – 42) + 5 = 25 + 5 = 30 → Does not follow the pattern (28, 59, 36) à (59 – 28) + 5 = 31 + 5 = 36 → Follows the pattern (44, 85, 47) à (85 – 44) + 5 = 41 + 5 = 46 → Does not follow the pattern Hence, the correct answer is (C).
A man can swim at the rate of 5 km/hr in still water. If the speed of the water is 2 km/hr, then the time taken by him to swim 18 km upstream is
A kayaker covers 64 km upstream and 96 km downstream in 8 hours and 6 hours, respectively. Find the time taken by the same kayaker to cover 140 km in st...

Speed of boat is 15 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 108 km downstream?
A boat takes half the time to move a certain distance downstream than upstream. the ratio of the boat's speed in still water and that of the current is.
