Work & Wages Questions and Answers

Q: In a regular week, there are 5 working days and for each day, the working hours are 8. A man gets Rs. 2.40 per hour for regular work and Rs. 3.20 per hours for overtime. If he earns Rs. 432 in 4 weeks, then how many hours does he work for ?

He works 175 hours.Regular hours in 4 weeks are 4 × 5 × 8 = 160. The earnings separate into regular pay and overtime:\[ \begin{aligned} 160 \times 2.40 &= 384 \\ 432 - 384 &= 48 \\ 48 \div 3.20 &= 15 \text{ overtime hours} \end{aligned} \]So he works 160 + 15 = 175 hours. 160 counts only the regular hours, and 180 and 195 would mean more overtime than Rs. 48 pays for.

Q: The daily wages of A and B respectively are ₹ 3.50 and ₹ 2.50. When A finishes a certain work, he gets a total wage of ₹ 63. When B does the same work, he gets a total wage of ₹ 75. If both of them do it together, what is the cost of the work ?

The cost is ₹ 67.50.A takes \(\frac{63}{3.50} = 18\) days and B takes \(\frac{75}{2.50} = 30\) days to do the work alone. Together they do\[ \begin{aligned} \frac{1}{18} + \frac{1}{30} &= \frac{5 + 3}{90} = \frac{8}{90} \\ \text{days} &= \frac{90}{8} = 11.25 \end{aligned} \]Their combined daily wage is ₹ 6, so the cost is \(11.25 \times 6 = 67.50\). Averaging the two totals gives ₹ 69, and the other options do not follow from the times.

Q: Working alone A can do a task in 27 hours and B can do the same in 54 hours. Find C's share (in ₹) if A, B and C get paid ₹ 4,320 for completing a task in 12 hours on which they worked together.

C's share is 1,440 rupees.In 12 hours A does \(\frac{12}{27} = \frac{4}{9}\) of the task and B does \(\frac{12}{54} = \frac{2}{9}\). C must do the rest:\[ \begin{aligned} 1 - \tfrac{4}{9} - \tfrac{2}{9} &= \tfrac{3}{9} = \tfrac{1}{3} \\ \text{C's share} &= \tfrac{1}{3} \times 4320 = 1440 \end{aligned} \]Payment is divided in proportion to work done. 1,920 is A's share and 960 B's.

Answer: B

He works 175 hours.

Regular hours in 4 weeks are 4 × 5 × 8 = 160. The earnings separate into regular pay and overtime:

\[ \begin{aligned} 160 \times 2.40 &= 384 \\ 432 - 384 &= 48 \\ 48 \div 3.20 &= 15 \text{ overtime hours} \end{aligned} \]

So he works 160 + 15 = 175 hours. 160 counts only the regular hours, and 180 and 195 would mean more overtime than Rs. 48 pays for.

Answer: A

The cost is ₹ 67.50.

A takes \(\frac{63}{3.50} = 18\) days and B takes \(\frac{75}{2.50} = 30\) days to do the work alone. Together they do

\[ \begin{aligned} \frac{1}{18} + \frac{1}{30} &= \frac{5 + 3}{90} = \frac{8}{90} \\ \text{days} &= \frac{90}{8} = 11.25 \end{aligned} \]

Their combined daily wage is ₹ 6, so the cost is \(11.25 \times 6 = 67.50\). Averaging the two totals gives ₹ 69, and the other options do not follow from the times.
