The cost of 5 tables and 6 chairs is Rs.2,884. What is the cost of 15 tables and 18 chairs?
(a) Rs.3300 (b) Rs.7332
(c) Rs.5600 (d) Rs.8652
(e) of these

Answer 1

(d) Let the cost of a table be = Rs.x and that chair be = Rs.y

According to the question,

5x + 6y = Rs.2884

3 × 5x + 3 × 6y = 3 × Rs.2884

or, 15x + 18y = Rs.8652
