Question

what is the singke discount equal to a seriea of 15% and 10% ?​

Answer 1

Answer:

3/2 ℅

Step-by-step explanation:

Let the marked price of any article be Rs. "x".

Now, let's calculate simplified value if first discount,

15℅ of x

= (15/100) * x

= (3/20) * x

= 3x / 20

Again, for simplified value of second discount,

= 10℅ of (15℅ of x)

= 10℅ of (3x / 20)

= ( 10 / 100 ) * ( 3x / 20 )

= ( 1 / 10 ) * ( 3x / 20 )

= 3x / 200

Hence, for single discount,

{ (3x/200) / x } * 100

= ( 3x / 200x ) * 100

= ( 3 / 200 ) * 100

= 3 / 2 ℅
