John buys 5 shirts and 3 trousers from a garment store at ₹900. In the following week, when the store offers a discount of 10%
on the same brand of the shirt and a discount of 25% on the same brand of the trouser, Jacob buys 5 shirts and 2 trousers for ₹630. Find the price at which John buys a trouser.
5 s + 3 t = 900 10% discount = 90% price 25% discount = 75% of original price
5 s .9 + 2 t*.75 =630
4.5s + 1.5 t = 630 two equations (in red) , two unknowns ....do you know how to solve?
