Study the given bar-graph and answer the question that follows. What is the ratio of the number of engineers in countries above the average to the number of engineers in countries below the average?
62/25
Step 1 – Read values from graph: Bhutan 20, Nepal 25, Japan 55, Australia 65, USA 85, India 98.
Step 2 – Average: \(\dfrac{20+25+55+65+85+98}{6} = \dfrac{348}{6} = 58\).
Step 3 – Group: Above 58 → 65 + 85 + 98 = 248. Below 58 → 20 + 25 + 55 = 100.
Step 4 – Ratio: \(\dfrac{248}{100} = \dfrac{62}{25}\).
Hence 62/25, option 3.
