Question

If two successive discounts are given 20% and 30% then what is net discount (in %)

Answer 1

lets assume initial price is 100 rs.
after 20% discount new price = 80rs.
now 30 % discount new price = 56 rs.
so in total you got 44% discount.

Answer 2

The net discount is 44 percent(%).

Step-by-step explanation:

Let initial price = Rs.100

To find, net discount (in %) = ?

1st discount = 20 % of 100 =$\dfrac{20}{100}  \times 100$ = 20

∴ After Discount = 100 -20 = Rs. 80

2nd discount = 30% of 80 =$\dfrac{30}{100} \times 80$= 24

After Discount = 80 - 24 = 56

Over all Discount = 100 - 54 = 44

Overall Discount ( in %)

= $\dfrac{Overall discount}{Initial discount}$ × 100

=$\dfrac{44}{100} \times 100$

= 44 %

Hence, the net discount is 44 percent(%).
