under a dripping tap

by sanju09 » Sat Jul 24, 2010 6:09 am
A bucket was placed under a dripping tap which was dripping at a uniform rate. At what time was the bucket full?

1. The bucket was put in place at 2 pm.
2. The bucket was half full at 6 pm and three-quarters full at 8 pm.

stmt1,

We know the time it was placed.But we dont know the rate.

Insufficient.

Stmt2,

1/2 =6 pm

3/4 = 8 pm

So rate 1/4 in 2 hrs.

It ll be full at 10 pm

Hence B
