Answer & Explanation

1.     (5) Difference = 52500 – 47500 = 5000
2.    (1) Required percentage =( 25/35) X 100 = 71.43 %
3.     (5) Required percentage = [( 42.5 – 37.5)/(37.5)]X 100= 13.33 %
4.    (3) Required ratio = (45 – 42.5) : (37.5 – 30) = 1 : 3
5.    (4) Required average = (35000 + 37500 + 42500 + 45000 + 47500 + 52500)/6  =43330 (approx).
