Question

13. Find a single discount equivalent to two successive discounts of 30% and 10℅​

Answer 1

Answer:

Let the amount be 100

After discount of 30%

100-30% of 100=70

After discount of 10 %

70-10% of 70 = 63

Now,

100-63=27

Let the successive discount be x,

x% of 100 =27

100x=2700

x = 27
