Question 8: A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is: (railway 2002)
(a) 6 hrs
(b) 10 hrs
(c) 15 hrs
(d) 20 hrs
Answer: Suppose, first pipe alone takes x hours to fill the tank .
Then, second and third pipes will take (x -5) and (x - 9) hours respectively to fill the tank.
x - 5 + x = 1
x(x - 5) (x - 9) = 1
(2x - 5)(x - 9) = x(x - 5)
(x - 15)(x - 3) = 0
x = 15. [neglecting x = 3]
Question 9: A can run 22.5 m while B runs 25 m. In a kilometre race B beats A by

B beats A by 100 m.
Question 10: What was the day on 13th April 1999?
Answer: 13th April, 1999 = (1998 years + Period from 1.01.199 to 13.04.1999)
Counting of odd days:
Numbers of odd days in 1600 years = 0.
Numbers of odd days in 300 years = (5 × 3) = 15 = 1.
(When 15 is divided by 7, it gives 1 as the remainder.)
98 years = (24 leap year + 74 ordinary years) ⇒ (24 × 2 + 74 × 1) = (48 + 74) = 122 days.
⇒ 122 days = (17 weeks + 3 day) = 3odd days
∴ 1998 years have = (0 + 1 + 3) = 4 odd days.
Jan Feb Mar April
31 + 28 + 31 + 13 = 103 days
⇒ 103 days = (14 weeks + 5 days) = 5 odd days
∴ Total number of odd days = (5 + 4) = 9 = 2.
Hence, the required day is Tuesday.
