Question

The price of a table and a chair are in the ratio $7:5$. If a table costs Rs. $480$ more than the chair, then the price of the chair is ____________.

• A. Rs. $600$
• B. Rs. $1000$
• C. Rs. $1200$
• D. Rs. $1800$

Answer 1

The correct option is C Rs. $1200$

Let the cost of table$=Rs.7x$
and the cost of chair$=Rs.5x$
According to question,
$7x=480+5x\Rightarrow 7x-5x=480$
$\Rightarrow 2x=480\Rightarrow x=\frac{480}{2}=240$
$\therefore$ Cost of chair $=Rs.(5\times 240)=Rs.1200$.
