Time taken by 5 women to do a work = 36 days
Time taken by 1 women to do the same work = 36 × 5 = 180 days
According to the given information,
Man/Woman = 3 : 1
Man = (1/3) × Woman
⇒ Time taken by 1 men to complete the same work = 1/3 × 180
∴ Time taken by 5 men to complete the same work = (1/5) × 1/3 × 180 = 12 days
Time taken by 1 women to do the same work = 36 × 5 = 180 days
According to the given information,
Man/Woman = 3 : 1
Man = (1/3) × Woman
⇒ Time taken by 1 men to complete the same work = 1/3 × 180
∴ Time taken by 5 men to complete the same work = (1/5) × 1/3 × 180 = 12 days
