Let the number of apples be= a
then,
number of guavas= a + (a X 60%)
=a + 3a/5
=8a/5
number of oranges= 8a/5 - (8a/5 X 12.5%)
=8a/5 - a/5
=7a/5
total no. of fruits=80
no. of apples + no. of guavas +no. of oranges = 80
a + 8a/5 + 7a/5 = 80
20a/5 = 80
4a = 80
a = 80/4
a = 20
apples = a = 20
guavas = 8a/5 = 8X20/5
=32
oranges = 7a/5 = 7X20/5
=28
