A) Rs.1.500
B) Rs.5, 100
C) Rs. 6,000
D) Rs.7, 500
Correct Answer: D
Solution :
C.P. of 1 computer table = Rs. x C.P. of 1 chair = Rs. y According to the question, \[3x+5y=25500\] ..... (i) \[2x+9y=\text{ }25500\] ..... (ii) Clearly, cost of 1 computer table = cost of 4 chairs From equation (i). \[3\times 4y+5y=25500\] \[\Rightarrow \] \[17y=25500\] \[\Rightarrow \] \[y=\frac{25500}{17}=1500\] \[\therefore \] Cost of 1 computer table \[=4\times 1500=Rs.\,6000\] \[\therefore \] Required answer \[=(6000+1500)=Rs.7500\]You need to login to perform this action.
