A) Rs. 3750
B) Rs. 3840
C) Rs. 3500
D) Rs. 3900
Correct Answer: D
Solution :
According to question, Price of 4 tables = price of 10 chairs \[\therefore \]Price of 2 tables = price of 5 chairs and price of 3 tables \[=\frac{10}{4}\times 3\] = price of \[\frac{30}{4}=\frac{15}{2}\]chairs Again, Price of 15 chairs and 2 tables = Rs. 4000 \[\Rightarrow \]price of 15 chairs + 5 chairs = Rs. 4000 \[\Rightarrow \] price of 20 chairs = Rs. 4000 \[\therefore \] Price of 1 chair \[=\frac{4000}{2}\]= Rs. 200 \[\therefore \] Price of 12 chairs and 3 tables = Price of 12 chairs + Price \[=\frac{15}{2}\]chairs = Price of \[\left( 12+\frac{15}{2} \right)=\frac{39}{2}\] chairs \[=\frac{39}{2}\times 200\] = Rs. 3900
