Answer 1

Answer:

The cost of 12 chairs and 4 tables is 7200 RS.

Option D)7200

Step-by-step explanation:

According to first statement cost of 12 chairs is equal to cost of 8 tables.

Let x be the cost of a chair and y be cost of a table.

12x = 8y

According to second statement cost of one table is 600Rs .

Cost of 8 tables = 12 chairs

8y = 12x

8 × 600 = 12x

4800 = 12x

x = 4800 ÷ 12

x = 400

So cost of one chair is 400Rs.

So cost of 12 chairs and 4 tables is

= 12x + 4y

= 12 × 400 + 4 × 600

= 4800 + 2400

= 7200

There for the cost of 12 chairs and 4 tables is 7200 RS.
