A) 15%
B) 16%
C) 14%
D) 12%
Correct Answer: A
Solution :
[a] Printed price = Rs. 320, \[{{d}_{1}}=10%\] Let\[{{d}_{2}}=x%\]Amount actually paid =Rs. 244.80 So, amount actually paid =\[\left( 1-\,\frac{10}{100} \right)\,\,\left( 1-\,\frac{x}{100} \right)\times 320\] \[244.80=\frac{90}{100}\times \frac{(100-\,x)}{100}\times 320\] \[100-\,x=\frac{244.80\times 100\times 100}{90\times 320}=85\Rightarrow \,\,x=15%\]You need to login to perform this action.
