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.
