Question

which is a better discount, two successive discount of 10% and 5% or a single discount of 15%
​

Answer 1

Answer:

15% at once

Step-by-step explanation:

Let the price of the object be 100 INR.

Then in the 1st part. The object is at discount of 10%.

Value of object after 10% discount:

=> (100-10)=90 INR

Again after that we see a second discount of 5%, so the value of object now is:

=> (90-(90*0.05))=85.5 INR.....................(1)

Now in the order part the discount was given of 15%, so current price is:

=> (100-15)=85 INR...........................(2)

Hence disount of 15% was more.
