For Rs. 25,500, a furniture shop sells 3 computer tables and 5 chairs OR 2 computer tables and 9 chairs. If one wants to buy a set of only 1 computer table and 1 chair, how much does he need to pay?

1. Rs. 1,500
2. Rs. 5,100
3. Rs. 6,000
4. Rs. 7,500

Correct Option: D

Let C.P. of 1 computer table = Rs. p
C.P. of 1 chair = Rs. q
According to the question,
3p + 5q = 25500 ..... (i)
2p + 9q = 25500 ..... (ii)
Clearly, cost of 1 computer table = cost of 4 chairs From equation (i),
3 × 4q + 5q = 25500 ⇒ 17q = 25500

⇒ q =	25500	= 1500
	17

∴ Cost of 1 computer table = 4 × 1500 = Rs. 6000
∴ Required answer = 6000 + 1500 = Rs. 7500
