ANSWERS:

1. 4
Average percentage of marks (of girls)
= (72 + 76 + 48)/3 = 65.33

2. 5
Marks obtained by the boys (in Hindi)
= (75% of 60) + (65% of 60) + (70% of 60)
= 45 + 39 + 42 = 126

Marks obtained by girls
= (65% of 60) + (75% of 60) + (45% of 60)
= 27 + 39 + 45 = 111
Reqd Difference = 126 - 111 = 15

3. 3
In Hindi, she has got only 39 marks.

4. 2
Total marks gained by Rani
= (90% of 120 + 48% of 75 + 75% of 60 + 68% of 75 + 76% of  150 + 88% of 50
= 108 + 36 + 45 + 51 + 114 + 44 = 398

5. 3
Avg in Eco =
(92 + 80 + 52 + 64 + 88 + 68)/6 of 75
= 444/ 6*100 * 75 = 5505

6. 2
(70 - 64)/70 * 100 = 60/7 = 8 4/7%

7. 5
Average = (55 + 48 + 75 + 50)/4 = 228/4 = 57

8. 3
= (70 + 64 + 45 + 60 + 6 0 + 73)/6 = 372/6 = 62
Maximum = 73
Ratio = 73:62

9. 3
Production of India = 372
Production of Sri Lanka = 350
Diference = 372 - 350 = 22
