Question

A farmer farms 800 apples in his farm every week and delivers them equally to 10 shops.
The shopkeepers charge Rs. 10 for every good apple but they have to give Rs.6 to the customer if the apple comes out to be rotten. A shopkeeper could only earn Rs.250 despite selling all the apples. How many apples were rotten?​

Answer 1

Answer:

no. of apple sold to every shopkeeper is equal to 800/10=80

let the no. of rotten apple =x

then, no. of good apple=80-x

then, (80-x)10-6x=250

800-10x-6x=250

800-16x=250

16x=550

x=550/16

x=34.375

so no. of rotten apple =34(approx.)
