Question

3men and 16 women can complete a piece of work in 4 days, 2 men and 4 women can do the same in
12 days. How long will it take a man to do it alone?
​

Answer 1

Answer:

44

Step-by-step explanation:

let the time taken by the man be X and woman be Y respectively.

So, ACCORDING TO THE QUESTION

3x+16y=4...........(1)

2x+4y=12

X+2y=6........(2)

NOW,

Eqn.1- Eqn.2......(BY ELIMINATION METHOD)

WE GET,

y=-7÷5......(3)

Now put 3 in 2

We get,

X+2(-7÷5)=6

x-14÷5=6

x-14=6×5

x-14=30

X= 30+14

X=44.

Therefore time taken by the man is 44 days
