Question

Express the given information in the form of an equation in mathematical form using two variables:

The cost of two tables and five chairs is Rs. 2200.

• A. $2x+5y=2200$
• B. $x+10y=800$
• C. $10x-5y=1800$
• D. Insufficient data

Answer 1

The correct option is A $2x+5y=2200$

Let the cost of one table be $Rs.x$ and that of one chair be $Rs.y$.

Hence, cost of two tables $=Rs.2x$ and cost of five chairs $=Rs.5y$

Given that, the cost of two tables and five chairs is $Rs.2200$.

$\therefore 2x+5y=2200$

Hence, option A is correct.
