 on the same brand of the shirt and a discount of 25% on the same brand of the trouser, Jacob buys 55 shirts and 22 trousers for ₹6300. Find the price at which John buys a trouser.

 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?
