Quantitative Aptitude : Time and Work
4 Man and 3 women finish a job in 6 days, and 5
men and 7 women can do the same job in 4 days. How long will 1 man and 1 women
take to do the work ?
Since (4men+3women)*6 days= (5men + 7women)*4days 24men days + 18 women days = 20 men days + 28 women days → 4 men days= 10 women days → 1 men days = 2.5 women days Total work = 24men days + 18 women days = 20 men days + 28 women days = 78 women days Hence, 1 man + 1 women =2.5 women + 1 women = 3.5 women can do it in 78/3.5 = 156/7 = 22 (2/7) days
Since (4men+3women)*6 days= (5men + 7women)*4days
ReplyDelete24men days + 18 women days = 20 men days + 28 women days
→ 4 men days= 10 women days
→ 1 men days = 2.5 women days
Total work = 24men days + 18 women days = 20 men days + 28 women days
= 78 women days
Hence, 1 man + 1 women =2.5 women + 1 women = 3.5 women can do it in 78/3.5 = 156/7 = 22 (2/7) days
