Question

2 table or 5 chairs cost Rs 2500. Determine the cost of 3 tables and 6 chairs.

Answer 1

Answer:

Step-by-step explanation:

2 tables = Rs 2500

1 table = Rs 2500/2

           = Rs 1250

5 chairs = Rs 2500

1 chair = Rs 2500/5

          = Rs 500

3 tables + 6 chairs

3(1250) + 6(500)

3750 + 3000 = 6750

Answer 2

Given :

2 table or 5 chairs cost Rs 2500

To Find :

Determine the cost of 3 tables and 6 chairs.

Solution:

2 table or 5 chairs cost Rs 2500

2 tables = 5 chairs

$1 table = \frac{2}{5} chairs\\3 tables =\frac{2}{5} \times 3 = \frac{6}{5} chairs$

So, 3 tables and 6 chairs =$\frac{6}{5}+6=\frac{36}{5} chairs$

cost of 5 chairs = 2500

cost of 36/5 chairs = $\frac{2500}{5} \times \frac{36}{5} = 3600$

Hence the cost of 3 tables and 6 chairs is Rs.3600
