40% of Indian people have traveled to the USA.
15% of Indian people are under the age of 30.
Now, required ratio \(= \frac {40}{15} = 8:3\)
So, the correct option is (B): \(8:3\)
Total overseas tourist from India,
\(= \frac {100}{20} \times 100\)
\(= 500\) Lakhs
Number of 30-39 years old Indian tourists who went abroad,
\(=\frac {15}{100} \times 500\)
\(=75\) Lakhs
So, the correct option is (D): \(75\) Lakhs.
Since the total number of people in the age group pie chart and those who have visited is unknown, we cannot determine the number of individuals aged 50 and above.
Do, the correct option is (D): Cannot be determined.
