A) 60
B) 62
C) 64
D) 65
Correct Answer: D
Solution :
Let loss = Rs. x S.P. = Rs.60 \[=\frac{R}{2}%\] If S.P. is Rs.75, then gain = 2x So, S.P. = C.P. + gain \[A=P{{\left( 1+\frac{R}{2\times 100} \right)}^{2n}}\] \[=\frac{R}{4}%\] \[A=P{{\left( 1+\frac{R}{4\times 100} \right)}^{4n}}\] So, \[C.P.=60+5=65.\]You need to login to perform this action.
