OPtion

1) Rs. 1200
2) Rs. 4200
3) Rs. 2400
4) Rs. 2100
5) Rs. 1800
6) Rs. 1500
7) Rs. 3000
8) Rs. 2700
9) Rs. 900
10) None of these

Solution

Let CP of a chair=C and a table=T
0.9C + 1.075T = T+C ⇒ 3T - 4C = 0 ---(i)
0.95T + 1.05C = T+C-15 ⇒ T - C = 300 ---(ii)
Solving eqn. (i) & (ii), we get T=1200, C=900
CP of a table and a chair = 1200+900 = 2100 Rs.
