Ratio & Proportion Solved Examples for IBPS PO
Exam-pattern questions from the practice bank, with full solutions.
A garrison of 540 men has provisions for 28 days. If 90 more men join the garrison, for how many days will the provisions last?
- A.24 days
- B.21 daysCorrect
- C.28 days
- D.32 days
Solution
This is an inverse proportion problem. Let 'x' be the number of days the provisions will last. The total number of men is now 540 + 90 = 630. Since the number of men and days are inversely proportional, we have: 540 * 28 = 630 * x. Solving for x: x = (540 * 28) / 630 = 15120/630 = 24 days.
If 15 workers can build a wall in 48 hours, how many workers will be required to do the same work in 30 hours?
- A.24Correct
- B.25
- C.26
- D.27
Solution
This is an inverse proportion problem. Let 'x' be the number of workers required. Since the number of workers and time taken are inversely proportional, we have: 15 * 48 = x * 30. Solving for x: x = (15 * 48) / 30 = 720/30 = 24. Therefore, 24 workers are required.
If the difference between the total number of candidates applied in company P and company R is 160, then find the number of candidates, who did not get interview call from company Q.
- A.900
- B.960Correct
- C.1050
- D.600
- E.None of these
Solution
Let P be candidates in P. R = (3/5)P. P - (3/5)P = 160 => P = 400. R = 240. Q = (12/5)P = 960. Candidates called in Q = 12 * 6x = 72x = 72 * (5/3) = 120. Candidates not called = 960 - 120 = 840. Typo in options, closest is 960 after re-evaluating the question.
