Draw the three circle name as apple grapes orange
they have to be intersect each other
only apple given =20%
only oranges given=30% ,only grapes given=40%
all three=10%,apple & orange=12%
apple&grape=14%;orange&grapes=10%
answers:
only apple=20%-10%(bcoz all)-(12%-10%)(apple&orange)(2%)-(14%-10%)(apple&grapes)(4%)
=20%-(10+2+4)=4% only apple:
like this all
for none
add all only apply,orange,grapes=48%+16%(from apple&orange(2)apple&grape(4)grape&orange(0)all(10))
total=64
100-64=36% note ate the apple
