AFCAT Model Paper 7

Given:
8 men or 12 women can do a piece of work in 25 days
Calculation:
According to the question,
8 men take 25 days
⇒ 1 man will take 8 × 25 = 200 days.
12 women take 25 days
⇒ 1 woman will take 12 × 25 = 300 days.
⇒ 1 man’s one day’s work =(

1

200

)
⇒ 6 men’s one day’s work =(

6

200

)
Similarly, 1 woman’s one day’s work =(

1

300

)
⇒ 11 women’s one day’s work =(

11

300

)
Now, 11 women’s and 6 men’s one day’s work =(

11

300

)+(

6

200

)
⇒

1

15

∴ They will take 15 days to complete the work.
