Hi there!
Here's the answer:

•°•°•°•°•°°•°•°•°•°•°

Let present agree of Raju's Father be f
Present age of Raju be r
& present age of Raju's Mother be m


•• After 6 years,
Raju's Fathers age = f+6
& Raju's age = r+6

Given,
Raju's Father age = 2(Raju's age)
=> (f+6) = 2(r+6)
=> f = 2r + 6


•• Two years ago,
Raju's mothers age = m-2
& Raju's age = r-2

Given,
Raju's Mother's age = 2×( Raju's age)
=> m-2 = 2(r-2)
=> m = 2r - 2



Sum of Raju's parent' s age is
=> f+m = 2r+6+2r-2
=> f+m = 4r+4
i. e., 4 more than 4times the Raju's present age.


•°• Sum of Raju's parent' s age is 4 more than 4times the Raju's present age.

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   
Devendra Marghade   6 years 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.

Please refer 'Today's puzzle'dated 11.03.2019.
I think option 175 is not correct.
He can divide every 12 minutes of his working in two parts
4 minutes for thinking and 8 minutes for typing.
Hence total 46 lines are typed in 12 minutes.
Then he takes rest for 6 minutes.
Hence in 18 minutes, he thinks and types 46 lines.
In 72 minutes , he will type 46*4=184 lines.

If this is puzzle site, think logical also.
If one has to calculate simply like 5th standard student, then it's your choice.
Do not make it 'M for murder of maths'.
