A) Rs.1200 |
B) Rs.1500 |
C) Rs.1800 |
D) Rs.2000 |
A) Rs.1200 |
A's 1 day's work = \( \Large \frac{1}{15} \)
B's 1 day's work = \( \Large \frac{1}{20} \)
C's 1 day's work = \( \Large \frac{1}{25} \)
A, B and C worked together.
Therefore, \( \Large \left(A+B+C\right) \)'s 1 day's work
= \( \Large \frac{1}{15} \)+\( \Large \frac{1}{20} \)+\( \Large \frac{1}{25} \)
= \( \Large \frac{20+15+12}{300} = \frac{47}{300} \)
Days taken to complete work by A, B and C working together
= \( \Large \frac{300}{47}\)
Therefore, Share of C = \( \Large \frac{1}{25} \times \frac{300}{47} \times 4700 \) = Rs.1200
