the rate of Rs.32 per kg, then what is the ratio of the incomes from the
exports?

a)
65 : 48 b) 31 : 42 c) 43 : 54

d) 57 : 62 e) 1 : 2

1.
Option 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.
Option 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.
Option 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.

**Quicker method**it is clear from the graph that the highest number of people died in UP.

4.
Option 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.
Option 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.
Option B

Productivity = Total Production / Area
of agricultural land

Productivity of UP = (35 + 30 + 25) x
1000 /
2 Lakh x 30/100 = 90000 / 60000 = 1.5 tonnes per sq km

Productivity of MP = (30 + 32.5 +
27.5) x 1000 / 2 Lakh x 25/100 = 90000 / 50000 = 1.8 tonne per sq km

Productivity of Bihar = (22.5 + 25 +
27.5) x 1000 / 2 Lakh x 20/100 = 75000 / 40000 = 1.875 tonnes per sq km

Productivity of Odisha = (22.5 + 15 +
10) x 1000 / 2 Lakh x 5/100 = 47.5 x 1000 / 10000 = 4.75 tonnes per sq km

Productivity of Haryana = (25 + 35 +
30) x 1000 / 2 Lakh x 8/100 = 90000 / 16000 = 5.625 tonnes per sq km

Productivity of Punjab = (40 + 30 +
35) x 1000 / 2 Lakh x 12/100 = 105000 / 24000 = 4.375 tonnes per

So, productivity
of Haryana is the maximum

7.
Option E

Production of Punjab is maximum =
105000 tonnes

8.
Option C

Production of Wheat in Punjab = 40000
tonnes

Production
of Maize in Odisha = 10000 tonnes

So, required % =
40000 – 10000 / 10000 × 100% = 300%

9.
Option D

The ratio of production of Rice in
Bihar to the production of Wheat in Haryana = 25000 tonnes : 25000 tonnes = 1 :
1

10. Option
A

Income of MP from export of 40% of Rice at
the rate of Rs.30 per kg = 32500 × 40/100 × 1000 × 30 = Rs.39 Crore

Income of UP
from export of 30% of Rice at the rate of Rs.32 per kg = 30000 × 1000 × 30/100
× 32 = Rs.28.8 Crore

So, required
ratio = 39 : 28.8 = 390 : 288 = 65 : 48
