Option 3 : Quantity I < Quantity II
Quantity I:
Pipe A's 1 hour's work = 1/15
Pipe B's 1 hour's work = 1/5
Leakage 1 hour's work = ¼
Pipe (A + B) and leakage 1 hours work = 1/15 – 1/5 – ¼ = -23/60
The tank will get empty in 60/23 hours.
Quantity II:
1 men 1 hour's work = 1/(20 × 25)
1 women 1 hour's work = 1/(30 × 15)
15 men 10 hours work = 15 × 1/(20 × 15) × 10 = ½
Remaining work = ½
30 women work = 30/(30 × 15) = 1/15
Total time in which 30 women can complete the half of the work = ½ × 15 = 15/2 hours.
Total works gets completed in = 10 + 15/2 = 35/2 hours
So, we can observe Quantity I < Quantity II.
