Q1.Direction: Study the following graph carefully and then answer the questions based on it. The percentage of five different types of electricity generation produced by a country during two years is given below.
If the production of wind electricity produced in 2014 was the same as that of 2015, what would have been its approximate percentage share in the total production of 2015?
Answer : Option BExplaination / Solution:
Production of wind electricity in 2014 = Production of wind electricity in 2015
∴ Production of wind electricity in 2014 = (100 – 85) % of 4250 = 637.5 TWh
Q2.Direction: Study the following graph carefully and then answer the questions based on it. The percentage of five different types of electricity generation produced by a country during two years is given below.
What is the maximum percentage increase in any kind of electricity from 2014 to 2015?
Answer : Option DExplaination / Solution:
Clearly the maximum percentage increase is in solar electricity from 2014 to 2015
Solar electricity in 2014 = 10% of 4250 TWh = 425 TWh
Solar electricity in 2015 = 25% of 7940 TWh = 1985 TWh
Q3.Direction: Study the following graph carefully and then answer the questions based on it. The percentage of five different types of electricity generation produced by a country during two years is given below.
What is the difference between the production of electricity from water in 2014 & 2015?
Answer : Option CExplaination / Solution:
⇒ Percentage production of electricity from water in 2014 = 25% of 4250
⇒ Percentage production of electricity from water in 2014 = 1062.5 TWh
Production of electricity from water in 2015 = 30% of 7940
⇒Production of electricity from water in 2015 = 2382 TWh
