d) 1 : 1                         e) 1 : 2

10)  If MP exports 40% of Rice at the rate of Rs.30 per kg and UP exports 30% of Rice at 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
