Question

15% of apple were found rotten in a basket .if the number of rotten apple in the 48.find total number of apple ,total number of fresh apple and percentage of fresh apple.

Answer 1

total apple =48
rotten apple =15% =48/0.15=320

Answer 2

let the total number of Apple present in the basket be x
total number of root in Apple = 48
so,
15/100×x=48
0.15x=48
x=48/0.15
x=320
Total number of Apple present in the basket = 320

total number of fresh Apple present in the basket =total number of Apple minus rotten number of Apples

total number of fresh Apple = 320-48
=272



percentage of fresh Apple =100%-percentage of rotten apple
=100%-15%
=85%


or another technique to find percentage of fresh Apple

percentage of fresh Apple = number of fresh apples / number of Total apples×100

=272/320×100
=85%


hope it helps you enough my friend...
