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)
Good
i dont know where to post it.. so posting here.. there is something wrong in Ratio and proportion test 6 question 2 and answer is wrong in question 3..
It would have been better if the data representation was accurate rather than expecting us to take the decimal values for granted
Hey Venkat, feedback noted. We will improve the graph a wee-bit and work on some better representation. Though, on a side note, you should be ready for such tricky representations in the exam.
Thnx for the response 🙂
Please solvr problem of di from sbi po mains this year
