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

Step 1: Calculate cost of $4$ burgers and $14$ macpuffs

Given: Cost of $1$ burger $=$ Rs $20\frac{3}{4}$

Cost of $1$ macpuff $=$ Rs $\frac{151}{2}$

As, Cost of $1$ burger $=$ Rs $20\frac{3}{4}$

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

$=$ Rs $\left(\frac{80+3}{4}\right)=$Rs $\frac{83}{4}$

$\therefore$ Cost of $4$ burgers $=$ Rs $\frac{83}{4}\times 4$

$=$ Rs $83$

Cost of $1$ macpuff $=$ Rs $15\frac{1}{2}$

Rs $=\left(\frac{30+1}{2}\right)=$Rs $\frac{31}{2}$

Cost of $14$ macpuffs $=$ Rs $\frac{31}{2}\times 14$

$=$ Rs $217$

Step 2: Calculate total cost

$\therefore$ Total cost of $4$ burgers and $14$ macpuffs

$=$Rs$83+$Rs $217$

$=$Rs$300$

Hence, the cost of $4$ burgers and $14$ macpuffs is Rs$300$.
