Due to direct proportion we have:
Sol- 5 men = 7 women
1 men = 7/5 women
10 men = (7/5×10)women = 14 women
(10 men + 5 women = (14 women + 5 men)
Let Rs x money be earned
7/875=19/x
1/125=19/x
(1×x)=(125×19)
x=Rs 2375
Sol- 5 men = 7 women
1 men = 7/5 women
10 men = (7/5×10)women = 14 women
(10 men + 5 women = (14 women + 5 men)

7/875=19/x
1/125=19/x
(1×x)=(125×19)
x=Rs 2375
