Answer 2

Step-by-step explanation:

Correct Answer:

$A) Rs.1,660$

Description for Correct answer:

If the C.P. of 1 chair be Rs.x, then C.P of 1 table = Rs. (x + 210)

$5x + 3 (x + 210) = 3110$

$∴5x+3x+630=3110$

$=> 8x = 3110 - 630 = 2480$

$=>x=24808=310$

$∴ CP of two tables and two Chairs =2(x+x+210)=4x+420$

$=4×310+420=Rs.1660$
