If 3/5th of a cistern is filled in 1 minute, how much more time is required to fill the rest of it?

  1. 30 sec
  2. 36 sec
  3. 40 sec
  4. 24 sec
Show answer and solution

Correct answer: C. 40 sec

1. In 1 minute (60 sec) the rate fills 3/5 of the cistern. 2. The remaining part is 1 − 3/5 = 2/5 of the cistern. 3. Time for 2/5 = (2/5) ÷ (3/5) × 60 sec = (2/3) × 60 = 40 sec. _Source: RRB Group D (RRC) PYQ, held 27-10-2013, Q.42._

Pipes A and B can fill a tank in X minutes and 6 minutes respectively. Together they fill it in 1.5 minutes. Find X.

  1. 1 minute
  2. 4 minutes
  3. 5 minutes
  4. 2 minutes
Show answer and solution

Correct answer: D. 2 minutes

1. Combined rate: 1/X + 1/6 = 1/1.5 = 2/3. 2. 1/X = 2/3 - 1/6 = 4/6 - 1/6 = 3/6 = 1/2. 3. So X = 2 minutes. _Source: RRB Group D CEN-02/2018 PYQ, Q.20._

Show answer and solution

Correct answer: A. 10

1. Total work = 10 x 8 = 80 man-days. 2. To finish in 4 days, men needed = 80 / 4 = 20. 3. Extra men = 20 - 10 = 10. _Source: RRB Group D CEN-02/2018 PYQ, Q.63._
