Bihar Police Constable Model Paper 6

Given:
Work done by Men = 1.5 × work done by women
Women Manufactures jeans in a day = 20 Units
Total work to be done = 1200 units
Formula used:
Total work done = Work done by men + Work done by women
Time taken = Total work / rate of work (units/day)
Calculation:
Work done by women = 20 units/day
⇒ Work done by men = 1.5 × 20
⇒ Work done by men = 30 units/ day
Now, Total work = 1200 units
⇒ Work done by both men and women = 20 + 30
⇒ 20 + 30 = 50 units/day
⇒ Time taken = 1200 / 50
∴ Time taken = 24 days
Note:
(Men and women working in the factory are equal in number.)
