Question

There are 500 apples in a box, If 20% of the apples are found rotten. How many are good apple

Answer 1

Answer:

100 Apple

Step-by-step explanation:

See I will explain you logically

20%  of 500 Apples

can be simply done as 20 apples are rotten in every 100 apples

so instead of 100 here value is 500 and  500 is 5 times 100

so  20*5=100 apple

Hope this new trick you liked if not I will give you normal method too

20% of 500=20/100*500=20*5=100

Answer 2

Answer:

Total apples in the box = 500

Rotten apples = 20%

Good apples = 100% - 20% = 80%

                   

80% of 500 = (80:100)*500.

                    = (80*500.):100

                    = 40000:100 = 400

Ans) 400 apples
