C Suppose, first faucet alone takes x hours to fill the cistern. Then, second and third faucets will take (x - 5) and (x - 9) hours respectively to fill the cistern. 1/x + 1/(x - 5) = 1/(x - 9) (2x - 5)(x - 9) = x(x - 5) x2 - 18x + 45 = 0 (x- 15)(x - 3) = 0 => x = 15

Last answer:
ANSWER: C Explanation: Speed of 1st train = 210km/hr Speed of 2nd train = 150km/hr Here the two passenger trains are running in same direction, so Relative speed = (210 - 150)km/hr = 60km ... faster train = relative speed * time taken by train to pass = 50/3 * 81 = 1350m

Last answer:
C speed=2V1V2/(V1-V2) = 2*5*4/(5-4) =40 km/hr Distance= vt1 (1+v/v1) =40* 55/60(1+40/5) =40*11/12(1+8) =40*11/12*9 =330 km Therefore the distance is 330km
