A) 15%
B) 18%
C) 20%
D) 25%
Correct Answer: C
Solution :
Let the second discount be x%. Then, \[\frac{(100-x)}{100}\times \frac{85}{100}\times 12=8.16\] \[\Rightarrow \] \[51\,\,(100-x)=4080\] \[\Rightarrow \] \[51x=(5100-4080)=1020\]\[\Rightarrow \]\[x=20\] \[\therefore \] Second discount = 20%You need to login to perform this action.
