Answer 2

Answer:

The cost of 5 chairs and 8 tables is Rs 2418

Step-by-step explanation:

Given that if the cost of 20 chairs and 32 tables is Rs. 9672

we have to find the cost of 5 chairs and 8 tables.

Let the cost one chair is x

and the cost of a table is y

then the cost of 20 chairs and 32 tables is

$20x+32y=9672$

Divide whole equation by 4, we get

$\frac{20x}{4}+\frac{32y}{4}=\frac{9672}{4}$

$5x+8y=2418$

Hence, the cost of 5 chairs and 8 tables is Rs 2418
