Time Elapsed Since 12- 2.5 hrs = 150 mins
Rate of Filling= 2g/min
So, quantity filled = 300g (2*150)
Proportion filled in 150 mins= 16% (7/25-3/25 = 4/25= 16%) - (we derive 7/25 from 28%)

So, if 300g constitutes 16% of the total capacity, the total capacity would be 1875g ((100*300)/16) - So, Option A

total time elapsed is 150 mins
let total capacity be x
3x/25 + (150*2) = .28 *x
solve for x= 1875
option A

For 2.5 hours (From 12h to 2h30 pm), (28/100) - (12/100) = 16/100 of the pool is filled.
Therefore, full capacity of the pool will be filled in 2.5*100/16 = 15.625 hours = 15.625*60 minutes = 937.5 minutes
The capacity of the pool = 2*937.5 = 1875 gallons.
Answer (A) is correct.

12% to 28%, or 16% filled up in 2.5 Hours

Thus, in 2.5 hours no of gallons filled up is 2.5*2*60 = 300 gallons fileld up in 2.5 Hours, which represents 16%, so 100% represents 300/16*100 = 1875, Answer will be (A)
