Answers and Explanations

Answer 1: (c)

MonthRainfall
January0.4
February1.4
March2.2
April2.8
May2.4
June1.4
July2.0
Total12.6

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)

MonthRainfall
January0.4
February1.4
March2.2
April2.8
May2.4
June1.4
July2.0
Total12.6

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)

MonthRainfall
January0.4
February1.4
March2.2
April2.8
May2.4
June1.4
July2.0
Total12.6

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)
