Answers:

1-5): From the given information we get:

Now, from the above information we get

Passed

Fig III

Again from the above information we get:

Note that,

• Passed in Physics only implies failed in Mathematics and Chemistry only.
• Passed in Physics and Chemistry only implies failed in Mathematics only.

Failed

Fig IV

And, ? = 824 - (140 + 240 + 180) = 264

Thus, we get

Failed

Fig V

1. 2; 

See figure IV.

The number of required students = 1500 - 676 = 824

2. 3; 

See figure IV.

The number of required students = 140 + 120 + 160 = 420

3. 5; 

According to the given information, 206 students passed in all the three subjects.

This implies that the remaining (1500 - 206 =) 1294 students failed in at least one subject.

4. 1; 

See figure V.

5. 4; 

See figure II.

The required number of students = 190 + 180 + 240 + 160 + 120 + 140 + 206

= 1236

Or, from figure V,

the required number of students = 1500 - 264 = 1236

6. 2; Expenditure of Company A in 2001

= 40 * 100/130 = Rs. 30.76 lakhs

7. 4

8. 4

Income of Company C in 2000

= 36 * 130/100 = Rs. 46.8 lakhs

9. 3

Required ratio = 135 : 145 = 27 : 29

10. 1

Expenditure of Company D in 2000

= 51 * 100/145 = 35.17 lakhs

Profit = Income - Expenditure 

= 51 - 37.17 = Rs. 15.83 lakhs
