(A) % of pears increase. This is because total % remains at 100%, if sold 20% (half) of apples, % of apples will decrease and % of pears will increase
(B) by above logic, if apples decrease by 20%, pears increase by 20%. Originally, pears had 100-40=60%. Now pears have 60+20=80%
Hope this helps :-)

By convert % to ratio,
Apple = 40% = 2u
Pear = 60% = 3u
After
Apple = 1u
Pear = 3u
So, Pear remain unchanged questions.
