IBPS PO General Awareness: Work and Time questions with solutions

Q1. Ajeet and Bharni can complete a work in 12 days and 16 days, respectively. If they work together and receive Rs. 2100, what is Bharni's share?

1. Rs. 850
2. Rs. 900
3. Rs. 1000
4. Rs. 1100

Answer: Rs. 900

Ajeet's efficiency is 1/12 and Bharni's is 1/16, so their work ratio is 4:3. The total payment Rs. 2100 is divided in the ratio 4:3, so Bharni gets 3/7 of 2100.

Q2. The table below shows the number of HR employees, the ratio of HR to Finance employees, and the difference between the number of HR and Finance employees in four different companies A, B, C, and D. | Company | Number of HR employees | Ratio of HR to Finance employees | Difference between HR and Finance employees | |---------|------------------------|----------------------------------|---------------------------------------------| | A | X + 300 | 4:7 | 330 | | B | Y | 3:5 | 240 | | C | 500 | P:Q | 100 | | D | Z^2 + 380 | 8:5 | 480 | Note: In company C, the number of HR employees is more than the number of Finance employees. In company C, if the ratio P:Q is swapped and, after swapping, the number of senior employees in HR is 40% of the total number of HR employees and the number of junior employees in Finance is 50% more than the number of senior employees in Finance, then find the number of senior employees in company C.

1. 360
2. 370
3. 380
4. 390

Answer: 360

For company C, HR = 500 and HR is greater than Finance by 100, so Finance = 400. After swapping the ratio, the intended split leads to HR seniors being 40% of 500, i.e. 200, and the remaining conditions are used to derive the total senior count as 360 according to the keyed solution.
