Question

there are 80 employees in a company each male gets 19 per day and female gets 23 per day if rs. 1600 per day then find the number of female employees in the company​

Answer 1

Step-by-step explanation:

x= men

y=women

( x+y= 80 ) * 19

( 19x + 23y = 1600 ) -

19x + 19y = 1520

-19x -23y = -1600

19x cancelled out

19y -23y = 1520-1600

-4y=-80

y=-80/-4

No. of women = 20

Answer 2

Step-by-step explanation:

x = men

y = women

( x+y = 80 ) * 19

( 19x+23y = 1600)

19x + 19y = 1520

-19x - 23y = - 1600

9x is cancelled out

9y - 23y = 1520 - 1600

-4y = - 80

y = -80/4

so, the no. of women is = 20.
