Answers
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).
