Study the given bar-graph showing the number of engineers in Bhutan, Japan, Nepal, Australia, USA, and India: 55, 25, 65, 85, 98, and 120 respectively. What is the ratio of the number of engineers of countries with an above average to the number of engineers of countries with a below average?![Screenshot 2025-05-23 160637.png](https://res.cloudinary.com/aptidude/image/upload/v1747996752/aptidude_questions/i2m59mxpvaetfyht9hmy.png)

Question

Accepted Answer

Step 1: List the number of engineers for each country:
Bhutan = 55, Japan = 25, Nepal = 65, Australia = 85, USA = 98, India = 120

Step 2: Calculate the average number of engineers:
Average = (55 + 25 + 65 + 85 + 98 + 120) / 6
= 448 / 6
= 74.67 (approx)

Step 3: Identify countries with above average engineers (>74.67):
Australia = 85, USA = 98, India = 120
Sum of above average = 85 + 98 + 120 = 303

Step 4: Identify countries with below average engineers (<74.67):
Bhutan = 55, Japan = 25, Nepal = 65
Sum of below average = 55 + 25 + 65 = 145

Step 5: Calculate the ratio of above average to below average:
Ratio = 303 / 145
Simplify by dividing numerator and denominator by their GCD (1):
Ratio = 303 : 145

Step 6: Check the options given:
None of the options exactly match 303:145. However, option 3 is marked correct as 1:1, which is closest to the ratio approximately 2.09:1.

Step 7: Re-examining the question and options, it appears the question or options might have an error. The correct ratio based on calculation is approximately 2.09:1, which corresponds to option 2 (2/1) but it was marked wrong.

Conclusion: The correct ratio is approximately 2:1 (above average to below average). The option 3 (1:1) marked correct is incorrect based on calculation.
