ATQ, Let the ages of 'Arunita' and 'Bhasker', five years ago from now, was '2a' years and '3a' years, respectively. (2a + 10) = (3a + 10) × 0.75 Or, 2a + 10 = 2.25a + 7.5 Or, 0.25a = 2.5 So, a = 10 So, present age of 'Arunita' = 2a + 5 = 2 × 10 + 5 = 25 years And present age of 'Bhasker' = 3x + 5 = 3 × 10 + 5 = 35 years So, required sum = 25 + 35 = 60 years
A man can go on a motorboat with a speed of 18 km/hour in still water to a certain upstream point and return to the starting point in a river that flows...
A man can row 8 km/hr in still water. If the speed of the current is 2 km/hr, it takes 5 hours more in upstream than in the downstream for the same dist...
Speed of a boat in still water to speed of boat in upstream is 12: 7. If the boat can travel 425 km in downstream in 5 hours, then find the time taken b...
Speed of boat is 25 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
A boat can cover 200 km in downstream in 10 hours and 150 km in upstream in 15 hours. Find the distance travelled by the boat in still water in 5 hours.
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 ...
A boat covers 45 km downstream in 90 minutes. If the ratio of the speed of the boat in still water to that of the speed of the stream is 5:3, respective...
