Question

age and 50 percentage​

Answer 1

Single equivalent discount for successive discounts of 10% and 20%.

= \left ( 10+20-\frac{20\times 10}{100} \right )\% = 28\%

Single equivalent discount for 28% and 30%.

= \left ( 28+30-\frac{28\times 30}{100} \right )\% = 49.6\%

Answer 2

Step-by-step explanation:

Given data:

Discount, d1 =50%

Discount, d2 = 50%

Let the cost price of an article be 100.

a/q,

After 1st discount;

New Price = 100- 100×50%= 50

After 2nd discount;

Final price= 50- 50×50%= 25

Total discount= Cost price- Final price= 100- 25= 75

Hence, Single discount equivalent= 75
