Solution

## The correct option is A Rs. 1660Let, the cost of one chair = C and the cost of one table = T Then, 5C + 3T = 3110 ....... (1) and, T - C = 210 or, T = 210 + C ...... (2) On putting value of T in Equation (1), 5C + 3(210 + C) = 3110 ⇒ 5C + 630 + 3C = 3110 ⇒ 8C = 3110 - 630 ⇒C=24808=Rs.310 ∴ Cost of one table (T) = 210 + 310 = 520 Hence, the cost of two tables and two chairs = 2T + 2C =2×520+2×310 =1040+620 =Rs.1660  Suggest Corrections  9      Similar questions
