Farmer Ben picks 87 apples. 26 apples are green, 20 are yellow, and the rest are red. How many apples are red?

The correct answer is: 41

26 + 20 = ?
26 + 20 = 46

87 – 46 = ?
87 – 46 = 41
So, 41 apples are red.

answer=41
total apple =87
green apple =26
yellow apple =20
lets assume there was 'x' red apple
as we are given that total apple =87
red apple + green apple + yellow apple=87(total apple)
x+26+20=87
x+46=87
x=87-46(we are given rest apple are red in color)
x=41
