Let the sum invested be 1000k. Amount after 1 year = 1000k × 1.1 = 1100k Sum after 2 years = 1100k × 1.1 = 1210k Interest of 2nd year = 1210k – 1100k = 110k Sum after 3 years = 1210k × 1.1 = 1331k Interest of 3rd year = 1331k – 1210k = 121k => 121k – 110k = 1210 ⇒ 11k = 1210 ⇒ k = 110 Hence, X = 1000 × 110 = Rs. 110000
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...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
A boat travels upstream at a speed of 10 km/h and downstream at 15 km/h. If the boat travels 30 km upstream and then returns, how much time does it take...
The speed of a boat in still water is 12 km/h and the speed of the current is 3 km/h. A person travels 270 kilometers in a boat in the upstream directio...
The speed of a boat in still water is 32km/hr and the speed of the current is 8km/hr. It takes a total of 15hours to row to upstream from Point A to B a...
The time taken by a boat to cover 72 km downstream is 3 hours less than the boat to cover a certain distance in upstream. The dow...
A man can row at 36 km/hr in still water. In a stream which is flowing at 12 km/hr, it takes him 3 hrs to a place and back. How far is the place?
A boat can travel 10 km more in downstream than that in upstream, in 5 hours while the difference between the time taken by the same boat to travel 250 ...
A man can row his boat with the stream at 14 km/h and against the stream in 8 km/hours. Find the rate of the stream.
The ratio between the time taken by a boat to cover a certain distance in upstream and the same distance in downstream is 5:1 respectively. The same boa...
