**Solutions:**

**1. C)**The number of people who died in train accidents in 2013 = 400 + 500 + 600 + 700 = 2200

The number of people who
died in train accidents in 2011 = 100 + 200 + 600 + 700 = 1600

So, required % = 2200 –
1600 x 100 / 1600 = 37.5%

**2. C)**Average number of people who died in train accidents in all states in 2008 = 1/4 × (100 + 200 + 300 + 500) = 1100/4 = 275

3. B) The number of
deaths in train accidents in Bihar = 100 + 300 + 300 + 200 + 500 + 600 + 400 =
2400

Similarly, in UP = 500 +
600 + 500 + 700 + 600 + 700 + 600 = 4200

In Maharashtra = 200 +
400 + 100 + 100 + 300 + 400 + 300 = 1800

In Odisha = 300 + 200 +
700 + 600 + 400 + 500 + 200 = 2900

In UP the number of people
who died in train accidents is the maximum.

**4. D)**The number of train accidents in 2014 = 200 × 18/100 = 36

The number of train
accidents in 2012 = 200 × 14/100 = 28

So, required difference =
36 ⎯ 28 = 8

**5. E)**The ratio of the number of deaths in 2010 to that in 2014 = (100 + 300 + 500 + 700) : (200 + 300 + 400 + 600) = 1600 : 1500 = 16 : 15

**6. B)**Total number of graduate employees working in Department A = 8000 × 12.5/100 × 27/100 = 8 × 1.25 × 27 = 270

**7. D)**Total number of non – graduate employees = [8000/(100 × 100)][ 12.5 × 73 + 16 × 55 + 22 × 67.5 + 18.5 × 45 + 14 × 65 + 17 × 52.5] = 0.8(912.5 + 880 + 1485 + 832.5 + 910 + 892.5} = 0.8 × 5912.5 = 4730

**8. C)**Total number of graduate employees working in Department E = 8000 × 14/100 × 35/100 = 392

Therefore Required
Percentage = 392/8000 × 100 = 4.9%

**9. B)**Total number of graduate employees working in Department D = 8000 × 18.5/100 × 55/100 = 814

Total number of non –
graduate employees working in Department D = 8000 × 18.5/100 × 45/100 = 666

Therefore required percentage
= (814 – 666)/666 × 100 = 14800/666 = 22.22% ≈ 22% more

**10. B)**Total number of non – graduate employees = 4730 (see explanation no. 9)

Total number of graduate
employees = 8000 – 4730 = 3270

Therefore, Required
average =3270/6 = 545
