Question

A $VCR$ is brought for $Rs.5500$ and sold for $Rs.6500$. Find:
The ratio of the price at which it was brought to the price at which it sold.
A $TV$ was brought for $Rs.7000$ and sold for $Rs.8400$. As per Pankaj, the ratio of buying price to selling price of the $TV$ and $VCR$ are same. Is he correct? Justify your answer with suitable reasoning.

Answer 1

For $VCR$,

Buying price $B=Rs.5500$

Selling price $S=Rs.6500$

$\frac{B}{S}=$$\frac{5500}{6500}=\frac{11}{13}$

For $TV$,

Buying price $B=Rs.7000$

Selling price $S=Rs.8400$

$\frac{B}{S}=$$\frac{7000}{8400}=\frac{5}{6}.$

Hence, Pankaj is incorrect because the ratio of buying price to selling price of the

$TV$ and $VCR$ are not same.
