(b)
A laptop cost Rs. 645 more than a printer
. 2 such laptops and 3 such printers cos
2470 altoghether. How much does 1 such laptop cost?​

Answer 1

Answer:

let cost of laptop = x

cost of printer = x+645

ACCORDING TO STATEMENT

2(x)+3(x+645) = 2470

2x+3x+1935 =2470

5x+1935= 2470

5x = 2470-1935

5x =535

x=535/5

x = 107

therefore cost of one laptop is Rs.107
