    Explanation:

    Amount of water fill by tap Q in 60 min = 25% of 400 = 100 l

    Flow rate of tap Q = 100/60 = 5/3 l/m

    Amount of tank filled in 21 min = (5/3) × 21 = 35 l
    For the flow rate of tap R,
    Amount of water fill by tap R in 60 min = 25% of 400 = 100 l
    Flow rate of tap R = 100/60 = 5/3 l/m
    Amount of water filled in 18 min = (5/3) × 18 = 30 l
    For the flow rate of tap P,
    Amount of water filled by tap P = 30% of 400 = 120 l
    Flow rate of tap P = 120/60 = 2 l/m
    Amount empty by tap P in 10 min = 10 × 2 = 20 l
    ∴ Final volume in tank = 35 + 30 - 20 = 45 l
