Solution:-

1. D

Required Ratio = 75+65 / 85+95 = 140/180 =7/9

2. C

150x100/205 = 73.17%

3. D

Required % = 245x3x100/ 280x3

= 350/4 = 87.5

4. B

Required Average= 1/6 x [80+75+95+85+75+70]

=> 1/6 x 480 = 80

5. D

6. C

Average = 3480

Hence, Required Ratio = 3:5

7. D

Required ratio = 5040/3360 = 1.5.

8. A

9. D

Average = 3480

Reserve for 1996-97 = 4320

Hence, required % = 4320x100/3480 = 124.137= 125(approx.)

10. A

1993-94 = 2520

1997-98 = 5040

Increase = 2520

% Increase = 2520x100/2520 = 100%
