Answer 1

Answer:

Step-by-step explanation:

given: the successive discounts are 20% and 40%

formula used:

succesive discount = x+y-(xy)/100

where,

x= 1st discount,

y=2nd discount

calculation:

succesive discount = x+y-(xy)/100

x=20%, y=40%

=> 20+40-800/100 => 52%

therefore, the single equivalent discount is 52%

hope it helps!

Answer 2

Answer:

Step-by-step explanation:

Given:

The successive discount are 20% and 40%.

Formula used:

Successive discount = X + Y - (XY)/100

Where,

X = First discount

Y = Second discount

Calculation:

Successive discount = X + Y - (XY)/100

X = 20%, Y = 40%

⇒ 20 + 40 - 800/100

⇒ 52%

∴ The single equivalent discount is 52%.
