There were 310 more women than men at a musical theatre. After 5/6 of the women and 3/4 of the men had left, there were 25 more women than men remaining behind. How many women were there at the musical theatre at first?

Let the number of women ==W

The number og men ==310  -  W

 

[1/6W]  =  [1/4 *[310 - W]] +25

 

W==246 - Number of women originally

310  -  246 ==64 - Number of men originally.

Sorry, I misread the question !! I took the number of men & women ==310.

 

Men ==M

Women ==M + 310

 

1 - 5/6 ==1/6 of women remaining

1 - 3/4 ==1/4 of men remaining

 

1/6 * [M + 310] ==1/4M + 25, solve for M

 

M==320 - Number of men originally

310 + 320 ==630 - Number of women originally.

6(x+25) - 4x = 310

2x = 310 - 150 = 160

 

4x + 310

= 320 +310

= 630
