Question

A, B, C rent an establishment for their different jobs. A puts 10 workers for 7 months, B puts 12 workers for 5 months and C puts 15 workers for 3 months for preparing jobs. If the rent of the establishment is Rs. 17500, how much must C pay as his share of rent?

• A. 4500
• B. 5500
• C. 5000
• D. 7000

Hint:

Share of rent is proportional to workers multiplied by months.

Answer 1

The Correct Option is A

Find the rent charged per unit of work first.
Total work units $= 70+60+45 = 175$.
Rent per unit $= \frac{17500}{175} = 100$.
C contributed $45$ units, so C's share $= 45 \times 100 = 4500$.
\[\boxed{Rs. 4500}\]
