Question

Cost of a burger is Rs. $20\frac{3}{4}$and of macpuff is Rs. $15\frac{1}{2}.$ Find the cost of 4 burgers and 14 macpuffs.

Answer 1

Cost of 1 burger $=Rs.20\frac{3}{4}=Rs.\frac{(20\times 4)+3}{4}=Rs.\frac{83}{4}$
$\therefore$ Cost of 4 burgers $=Rs.4\times \frac{83}{4}=Rs.83$
Cost of 1 macpuffs $=Rs.15\frac{1}{2}=Rs.\frac{31}{2}$
Cost of 14 macpuffs $=Rs.14\times \frac{31}{2}=Rs.217$
$\therefore$ Total cost of 4 burgers and 14 macpuffs $=Rs.(83+217)=Rs.300$
