Q.12. Santosh spends Rs. (7x - 4) for a shirt and Rs. (2x + 8) for a pair of trousers. If he gives the shopkeeper a Rs. 1000 note, how much will he get back?

$TheamountSantoshspendsforashirt=Rs.(7x-4)\phantom{\rule{0ex}{0ex}}TheamountSantoshspendsforapairoftrousers=Rs.(2x+8)\phantom{\rule{0ex}{0ex}}Totalamountspent=(7x-4)+(2x+8)=9x+4\phantom{\rule{0ex}{0ex}}HegivesRs.1000,Sohewillgetback1000-(9x+4)=996-9x$
