Question

13) Find the single discount equivalent to two
successive discounts of (i) 10% and 5%
(ii) 8% and 5%.​

Answer 1

Answer:

i) 14.5%

ii) 12.6%

Step-by-step explanation:

i)let the total be 100

90% of 95% of 100

=85.5

Now single discount =(100 - 85.5)%

=14.5%

ii) 92%of 95%of 100

Therefore,

=92/100 *95/100 *100

= 87.4

Therefore single discount =(100-87.4)% =12.6
