Question

If the total cost of $3$ chairs and $2$ tables is $Rs.1200$ and the total cost of $12$ chairs and $8$ tables is $Rs.4800$, then the cost of each chair can be $Rs.200$ and each table can be of:

• A. $Rs.200$.
• B. $Rs.300$.
• C. $Rs.400$.
• D. $Rs.500$.

Answer 1

The correct option is B $Rs.300$.

Let each chair cost Rs. $x$ and each table cost Rs. $y$.

Therefore, $3x+2y=1200$
Also, $12x+8y=4800\Rightarrow$ $3x+2y=1200$
So, the price of the chair and table can be $Rs.200$ and $Rs.300$ respectively, as this will satisfy the equations.
