B) 44%
C) 42%
D) 35%
Correct Answer: B
Solution :
(b): Let listed price be 'x' Price after 30% discount \[=x\times \left( 1-\frac{30}{100} \right)\] = 0.7x Price after second 20% discount \[=0.7x\left( 1-\frac{20}{100} \right)=0.56x\] \[\therefore \] Equivalent discount = \[\left( \frac{x-0.56x}{x} \right)\] \[=\frac{0.44x}{x}\] = 0.44 = 44%.You need to login to perform this action.
