|
B) 8 days |
|
C) 10 days |
|
D) 12 days |
Correct Answer:
| C) 10 days |
Description for Correct answer:
According to 'MAN-DAY-WORK' concept
\( \Large \frac{M_{1} \times D_{1}}{W_{1}} = \frac{M_{2} \times D_{2}}{W_{2}} \)
\( \Large \frac{15 \times 16}{1} = \frac{24 \times D_{2}}{1} \)
\( \Large D_{2} = \frac{15 \times 16}{24} = \frac{5 \times 16}{8} \)
\( \Large D_{2} = 10 \)days
