FIG

The table given below shows the number of cases per Million population in four countries.
Country - Cases/1 M
• Italy - 2453
• France - 1215
• Spain - 1466
• USA - 234
Cases per million = (Total cases × 1,000,000) /Population
Total cases = Active + Recovered

B. 24155
C. 25515
D. 23850

2. What is the ratio of the population of Italy to the population of Spain?

5. What is the difference between the Active cases of Italy and Spain?

A. 348
B. 424
C. 328
D. 358

Common Explanation:

1. From the common solution:
Active cases in France = 34020
Recovered Cases in France = 8505
Required difference = 34020 – 8505 = 25515
Hence, option C is correct.

2. From common explanation, we have
Required ratio = 4.8Cr : 9.6Cr = 1 : 2
Hence, option A is correct.

3. From common explanation, we have
Required difference = 52776 – 52416 = 360
Hence, option D is correct.

4. From common explanation, we have 37.5% population is uneducated so 62.5% population is educated. Educated people in USA = 62.5 × 224 Cr = 140 Cr 100
Hence, option B is correct.

5. From common explanation, we have
Required difference = 88308 – 87960 = 348
Hence, option A is correct.
