Question

the equivalent discount to consecutive discount of 15% and 20% will be??
a.35% b.36%
c.32% d.30%​

Answer 1

Answer:

Option 3, or C is the correct answer.

Step-by-step explanation:

Let $D_{1}$ = Discount 1, or 15%

Let $D_{2}$ = Discount 2, or 20%

Now use formula, $D=D_{1}+D_{2}-\frac{(D_{1}D_{2})}{100}$

So...

$D=15+20-\frac{15\times20}{100}$

D = 35-3

D = 32%
