If 6 women can complete a work in 3 days, and 9 girls can complete the same work in 2 days, then find the time taken to complete the same work by 8 women and 6 girls?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 9/7 days.
Calculations:
Let the number of women and girls be x and y
According to the question;
⇒ 6x × 3 = 9y × 2
⇒ x = y or x/y = 1/1
Hence, total work = 6 × 1 × 3 = 18
Required days = 18/(8 × 1 + 6 × 1) = 18/14 = 9/7 days
