c.p of each apple = 34/8 = 4.25
s.p of each apple = 57/12 = 4.75
profit per apple = 4.75-4.25 = 0.5
net profit = no of apple sold * profit on each apple
45 = no of apple sold *0.5
45/0.5 = 45*2 = 90 = no of apple sold
thus the answer is (A) 90 apples

Let the measure of the breadth =10
Let the measure of the length = 10
original area=10 x 10 =100
new length=9.5
new breadth=10.5
new area = (100-5)(100+5)/100
new area=99.75
percent change=100-99.75
=(0,25/100) x 100=0.25% decrease
