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 $=Rs.20\frac{3}{4}=\frac{(20\times 4)+3}{4}=\frac{83}{4}$

$\therefore$ 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 $=Rs.(83+217)=Rs.300$
