RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
Ram = ₹9,000 and Shyam = ₹6,000

Work Rate Calculation

Ram can complete the work in 12 days, and Shyam can complete it in 18 days. To find the ratio of the work they do, we can consider the least common multiple (LCM) of their days, which is 36.

  • In 36 days, Ram completes $36 / 12 = 3$ units of work.
  • In 36 days, Shyam completes $36 / 18 = 2$ units of work.

The ratio of work done by Ram to Shyam is $3:2$. This ratio determines how the total payment is divided.

Individual Earnings Calculation

The total amount received is ₹15,000. This amount should be divided in the ratio of work done, which is $3:2$.

  • Total parts in the ratio = $3 + 2 = 5$ parts.
  • Value of 1 part = Total Amount / Total Parts = $₹15,000 / 5 = ₹3,000$.

Now, calculate the individual earnings:

  • Ram's share = Ram's ratio parts × Value of 1 part = $3 \times ₹3,000 = ₹9,000$.
  • Shyam's share = Shyam's ratio parts × Value of 1 part = $2 \times ₹3,000 = ₹6,000$.

Therefore, Ram received ₹9,000 and Shyam received ₹6,000.
