# Important Data Interpretation Set – 99

D.1-5) Study the following graph carefully to answer the questions:

Production of wheat in different countries

Total Production=50 lakh Tonnes

Production: Scientific Vs Conventional Methods in Percentage

Q.1) What is the difference between the production by scientific method and conventional method in Indonesia?

a)  2.3 lakh tonnes

b) 2.8 lakh tones

c) 2.5 lakh tonnes

d) 3 lakh tones

e) None of these

a)  2.3 lakh tonnes

Production In Indonesia= 50 x 10/100= 5 lakh tones

Difference= 5 x ((73 – 27))/100= 2.3 lakh tones

Q.2) What is the average production of wheat by scientific method for all the countries?

a) 3.1 lakh tonnes

b) 4.24 lakh tones

c) 2.6 lakh tonnes

d) 3.07 lakh tones

e) None of these

b) 4.24 lakh tones

Production of wheat by scientific method in

India= 50 x (18/100)x (32/100)= 2.88 lakh tones

Japan = 50 x (20/100)x (78/100)= 7.8 lakh tones

China= 50 x (22/100)x (70/100)= 7.7 lakh tones

Bangladesh= 50 x (8/100)x (20/100)= 0.8 lakh tones

Pakistan= 50 x (9/100)x (66/100)= 2.97 lakh tones

Indonesia= 50 x (10/100)x (73/100)= 3,65 lakh tones

Sri Lanka= 50 x (13/100)x (60/100)= 3.9 lakh tones

So Average = (2.88 + 7.8 + 7.7 + 0.8 + 2.97 + 3.65 + 3.9)/7= 4.24 lakh tones

Q.3) What is the ratio of production by conventional method in Pakistan to that by scientific method in Japan?

a)  9/40

b) 99/260

c) 51/260

d) 48/77

e) None of these

c) 51/260

Production by conventional method in Pakistan = 50 x (9/100)x (34/100)= 1.53 lakh tones

Production by scientific method in Japan= 7.8 lakh tones

Required ratio= 1.53 : 7.8 = 51 : 260

Q.4) The production of wheat in Sri Lanka by Conventional method is approximately how many times the production in India by scientific method?

a) 1.2

b) 1.5

c) 0.9

d) 2.1

e) None of these

c) 0.9

Production of wheat in Sri Lanka by Conventional method= 50 x (13/100)x (40/100)= 2.6 lakh tones

Production in India by scientific method= 50 x (18/100)x (32/100)= 2.88 lakh tones

According to question, 2.88 X x = 2.6

x = 2.6/2.88= 0.9 times

Q.5) The production of wheat in India by Scientific method is approximately how many times the production in Pakistan by Conventional method?

a)  2.88

b) 2.07

c) 2.61

d) 0.81

e) None of these

e) None of these

Production of wheat in India by Scientific method= 50 x (18/100)x (32/100)= 2.88 lakh tones

Production of wheat in Pakistan by Conventional method=50×9/100×34/100=1.53

=2.88/1.53=1.88
