Question

Quantity-I: Pipe P can empty a full tank in 25 hours, while pipe Q can fill an empty tank in 40 hours. If the tank is initially 36% full, pipe P operates for 6 hours before being shut off. Determine how much time pipe Q will take to fill the remaining tank. Quantity-II: Determine the time a bus will take to cover a distance of 1080 km at a constant speed of 20 m/s.

Q: Answer-Quantity-I: Pipe P can empty a full tank in 25 hours, while pipe Q can fill an empty tank in 40 hour...

For Quantity I Initially, tank 36 full. P fills in 25 hours, so in 6 hours P fills 625 100 24. After 6 hours, tank filled 36 24 60. Remaining 40. Q fills the whole tank in 40 hours, so time to fill 40 40 40100 16 hours. Thus Quantity I 16 hours. For Quantity II 20 ms 72 kmh Time 108072 15 hours. Therefore, Quantity I Quantity II.

In the question, two Quantities I and II are given. You have to solve both the Quantity to establish the correct relation between Quantity-I and Quantity-II and choose the correct option.

A Quantity-I > Quantity-II

B Quantity I < Quantity II

C Quantity I = Quantity II or No relation can be established

D Quantity-I ≤ Quantity-II

E Quantity-I ≥ Quantity-II
