Cost of 18 shirts and 45 trousers is rs 68400 what is the cost of 10 shirts and 25 trousers

Answer 1

Answer:    10 Shirts + 25 Trousers = 38000 Rupees

Step-by-step explanation:

Let the cost of a shirt be S and the cost of a trouser be T.

So, 18S + 45T = 68400

We need to know the value of 10S + 25T.

In order to get that, multiply the above equation by 5/9.

It implies (18S + 45T)*5/9 = 68400*5/9

Or,  10S + 25T = 38000
