Answer:
correct option is F
Step-by-step explanation:
Suppose there is a book the cost of which is $100
You got successive discounts of 15% off and then 25% off
So after getting 15% discount cost of book=$85
again on $85 there is a discount of 25%
it means
25% discount on $85=[tex]\frac{25\times 85}{100} \\[/tex]
=$21.25
It means after successive discounts of 15% off and then 25% off cost of book=[tex]85-21.25[/tex]
after successive discounts of 15% off and then 25% off cost of book=$63.75
On the other hand if you got 40% discount on the same book which costs $100
then after discount of 40% its cost will be=$60
It means,Taking successive discounts of 15% off and then 25% off is not same as taking a one time discount of 40%.
Therefore correct option is F
