Explanation
Question 1-
Number of people tested positive in March = 2100.
Number of days in March = 31
Average =
2100/31= 67.74
Hence, option B is correct.
Question 2-
We can see that China, Italy and the USA showed more than 3000 positive tests.
Hence, option D is correct.
Question 3-
Number of people found positive in January = 740
Number of people found positive in February = 2480
Percentage growth = 2480 – 740/740x 100 = 235.13%
Hence, option B is correct.
Question 4-
Number of cases in India in January = 100
Number of cases in Japan in January = 2 × 100 = 200
Number of cases in February in India = 600
Number of cases in Japan in February = 600 + 50% of 600 = 900
Total cases in Japan till Feb end = 200 + 900 = 1100
Number of cases in March = 2 × 1100 = 2200
Hence, option C is correct..
Question 5-
Total number of cases in USA in February and March = (5600 + 10000) = 15600
Number of cases in China in February = 4250
Number of cases in Italy in March = 6250
Total = (4250 + 6250) = 10500
Required ratio = 15600 : 10500 = 52 : 35
Hence option (E) is correct.
