also that of each woman is same
find the total Salary of one man and two women​

Answer 1

The total salary of one man and two women is Rs. 51000

Step-by-step explanation:

Let the salary of one man be Rs. x and that of one woman be Rs. y

By the given conditions,

(5x + 4y)/(5 + 4) = 12000

or, 5x + 4y = 9 * 12000

or, 5x + 4y = 108000 ..... (1)

(7x + 8y)/(7 + 8) = 14000

or, 7x + 8y = 15 * 14000

or, 7x + 8y = 210000 ..... (2)

Taking (2) - (1), we get

7x + 8y - 5x - 4y = 210000 - 108000

or, 2x + 4y = 102000

or, x + 2y = 51000

Therefore the total salary of one man and two women is Rs. 51000
