The price of 10 chairs is equal to that of 4 tables. The price of 15 chairs and 2 tables together is Rs. 4,000. The total price of 12 chairs and 3 tables is
A
Rs. 3,500
B
Rs. 3,750
C
Rs. 3,840
D
Rs. 3,900
Correct Option:
D
Explanation
Let the price of one chair be C and one table be T. From 10C = 4T, T = 2.5C. Also, 15C + 2T = 4000, so 15C + 5C = 4000 and C = 200. Thus T = 500, and 12C + 3T = 12(200) + 3(500) = 3900.
