Total work = (4M+3W)*6 = (5M+7W)*4
4M=10W or M=(5/2)W
Total work expressed in terms of W = [4*(5/2)W + 3W]*6 = 78W
Now 1 day work of 1 man & 1 woman = (5/2)W + W = (7/2)W
Therefore, days required = 78/(7/2) = 22 2/7

Two workers undertake to do a job. The second worker started working two hour after the first. Five hours after the Second worker has begun working, there is still 9/20 of the work to be done. When the assignment is completed, it turns out that first worker has done 60% of the work while second worker has done rest of the work. How many hours would it take each one to do the whole job individually?

Reply Like? Yes | No

(2 Months ago)

Ans: 20 hrs, 25 hrs

Working alone, let 1st worker can do a job in 'A' hrs and 2nd worker in 'B' hrs, then
1st working for 7 hrs and 2nd for 5 hrs, completes 11/20 of the work.
=> 7/A + 5/B = 11/20 ---(i)
Let the work gets completed in 'x' hrs and 1st worker does 60% work => x/A=60/100 or 1/A=3/5x ---(ii)
2nd worker does 40% work in (x-2) hrs => (x-2)/B=40/100 or 1/B=2/[5(x-2)] ---(iii)
Now substituting value of 1/A & 1/B in eqn (i), we get 7*(3/5x) + 5*2/[5(x-2)] = 11/20
21/x + 10/(x-2) = 11/4
[21(x-2) + 10x]*4 = (x² - 2x)*11
124x - 168 = 11x² - 22x
11x² - 146x + 168 = 0
11x² - 132x - 14x + 168 = 0
(11x-14) (x-12) = 0
x = 14/11, 12, considering whole number x=12
Now substituting value x=12 in eqn (ii) & (iii), we get A=20, B=25
Therefore, 1st worker takes 20 hrs and 2nd worker takes 25 hrs, to do the job individually.
