Answer:

Correct Answer: A

Solution:

Let cost of 1 table be Rs. x and cost of 1 chair be Rs. y. Then, $ 3x+5y=3110 $ … (i) and $ y=x-210 $

$ \Rightarrow $ $ x-y=210 $ (ii) On solving Eqs. (i) and (ii), we get $ x=520 $ and $ y=310 $

$ \therefore $ Cost of 2 tables and 2 chairs $ =2x+2y=2(x+y) $ $ =2(520+310)=2(830)=Rs\text{.1660} $
