The price of a mobile is reduced by 35%. The new price is reduced by a further 30%. The two reductions together are equal to a single reduction of
a) 10.25%
b) 54.75%
c) 65%
d) 62.25%

If none of them, please specify the exact answer.

Detailed/ step-by-step explanation would be helpful.

• 54.5%
  
  Let the original price be 100, then after two gradual reductions, price = 100x(65/100)x(70/100)=45.5
  So on 100, single discount=100-45.5 = 54.5 or 54.5%
