Answers and Explanations
Answer 1: (c)
| Month | Rainfall |
| January | 0.4 |
| February | 1.4 |
| March | 2.2 |
| April | 2.8 |
| May | 2.4 |
| June | 1.4 |
| July | 2.0 |
| Total | 12.6 |
The ratio of rainfall in Feb : July = 1.4/2.0= 0.7:1 . The value of Column B is 2:3 = 0.67 : 1 . Since the value in column A is more than B, the correct option is (c)
Answer 2: (b)
| Month | Rainfall |
| January | 0.4 |
| February | 1.4 |
| March | 2.2 |
| April | 2.8 |
| May | 2.4 |
| June | 1.4 |
| July | 2.0 |
| Total | 12.6 |
The average annual rainfall is 12.6/7 = 1.8 ins which is less than 1.9 inch. Since the value in column B is more Than A, the correct option is (b)
Answer 3: (c)
| Month | Rainfall |
| January | 0.4 |
| February | 1.4 |
| March | 2.2 |
| April | 2.8 |
| May | 2.4 |
| June | 1.4 |
| July | 2.0 |
| Total | 12.6 |
Total rainfall in 7 months= 12.6= $12\frac{1}{2}%\,\,of\,\,12.6$ =$\frac{25\times 12.6}{200}=$ 1.575 inch
The amount of rainfall during the month of February = 1.4 inch
The value of the column A is more.
Therefore the correct option is (c).
Answer 4: (c)
Ratio of rainfall in May: January : 2.4:0.4 = 6:1
Ratio of rainfall in April : February : 2.8:1.4 = 2:1
The ratio of column A is more than the ratio of column B.
Therefore correct option is (c)
