Question

4 men and 4 women can finish a piece of work jointly in 3days while 2 men and 5 women can finish the same work jointly in 4 days find the time taken by one man alone and that of one women alone to finish the same work​

Answer 1

Answer:

Let work be complete by men be - X

Let work be complete by women be - Y

4/X + 4/Y = 1/3. / 1/X = A

2/X + 5/Y = 1/4. / 1/Y = B

4a+4b=1/3 (1)

2a+5b=1/4

Multiply EQ 2 by 2

4a+10b= 1/2 (3)

Now you can solve the equation by elimination then put value of b and a like this

1/X = whatever the value of a

1/Y = " " " " " " " "
