In how many ways can 600 be expressed as a sum of two or more consecutive natural numbers ?
Please explain
Guys please answer this!!!!! I tried a lot but failed. The correct answer is 60m.
A and B are stationed at Q and R respectively on a flowing river. The direction of flow is q to r. When a and b swim towards each other they meet at p which is 20m from R. When a swims towards b,bswims away from a and they meet at S which is 40m from R. B's speed in still water is 5 times the speed at which the river flows.
On a particular day A n B start swimming towards each other simultaneously from the points where they are stationed. When A was 'y'm away from P ,B turns back and they meet at R. Find y.
