**Questions are based on given line graph. read carefully and answer the following questions.**

**Question 1: In which of the following years was the percentage increase in income over the previous year the maximum?**

- 1989
- 1990
- 1991
- 1992

[spoiler show=”Answer with explanation”]

Slution: Percentage increase= 100 × Increase/Previous year income. Option 3 is eliminated because there is a decreasoe in income in 1991.

In 1989, percentage increase = 100 × 20/30 = 66.67%.

In 1990, percentage increase = 100 × 15/50 = 30%.

In 1992, percentage increase = 100 × 17.5/57.5 = 30.43%

(All the data is in Rs ’00 cr.) Thus, Option 1 is the answer.

Alternatively,

For maximum % change, numerator should be the greatest and the denominator should be smallest. The numerator for 1989 is the greatest, while the denominator for the same year is the lowest as compared to corresponding figures for 1990 and 1992. So, you need not to find the exact percent increase of all the options given. Hence, answer is 1st option.[/spoiler]

**Question 2: What was the average income of the company over the years (approximately)?**

**4500 cr****500 cr****5500 cr****550 cr**

[spoiler show=”Answer with explanation”] Average in Rs ’00 cr. = (30 + 50 +65 + 55 + 75 + 55)/6 = 55 =>Average= Rs 5500 cr. Hence, answer is 3rd option.[/spoiler]

**Question 3: What is the ratio of income to expenditure in the year 1990?**

- 1.2
- 1.3
- 1.1
- 1.4

[spoiler show=”Answer with explanation”]The income in the year 1990 is Rs. 6500 cr. and the expenditure is Rs. 5000 cr. Thus, the ratio in the year 1990 will be 6500/5000 = 1.3. Hence, answer is 2nd option.[/spoiler]

**Question 4: The total expenditure in 1988 and 1989 together was equal to the income in which of the following years?**

- 1900
- 1991
- 1993
- None of these

[spoiler show=”Answer with explanation”]The total expenditure in 1988 and 1989 together = Rs. 6000cr, which does not match with any other year’s expenditure. So, the correct answer will be Option 4.[/spoiler]
