How many hours will it take to fill the pool?
Need fill rate of P and T individually or combined
S1
Time needed by P = 28hr
No info on T
Insufficient
S2
T was turned on an hour later than P
Ok, but we don't know the fill rate of either
Insufficient
Combined, we just know the fill rate of P and that T was turned on an hour later than P. We still don't know the fill rate for T. Insufficient

The capacity of the pool is 45000 litres.
Hoses P and T fill the pool, we need to find the Time the pool is filled.
Statement 1:
(1) Hose P alone would take 28 hours to fill the pool.
Since, we don’t know the time take by both combined or pipe T.
It’s Insufficient.
Statement 2:
(2) Hose T was turned on an hour later than hose P.
The rate of P and T is not known. Nor is the time of P and T.
It’s Insufficient.
Combining both the Statements 1 and 2, we get
Time taken by pipe P = 28
Time taken by T =? , Time taken by both working together = ? ,Individual rates = ?
It’s Insufficient.
Option E
