The Correct Option is C
Solution and Explanation
Step 1: Pick the cities with longitude between \(10^\circ\) E and \(40^\circ\) E:
Check the longitude column: Vienna \(16.22^\circ\) E, Sofia \(23.20^\circ\) E, Tripoli \(13.07^\circ\) E, Warsaw \(21.0^\circ\) E and Lusaka \(28.16^\circ\) E. Every other longitude is below 10 (Accra \(0.6^\circ\) E, Dublin \(6.18^\circ\) E, Madrid \(3.45^\circ\) W) or above 40. So there are 5 such cities.
Step 2: Count those in the Southern Hemisphere:
Vienna, Sofia, Tripoli and Warsaw are in the north. Only Lusaka (\(15.28^\circ\) S) is in the south. So 1 city.
Step 3: Percentage:
\[\frac{1}{5} \times 100 = 20\%.\]
Final Answer:
The correct option is (3): 20%.

Question: 2
The number of cities whose names begin with a consonant and are in the Northern Hemisphere in the table
The number of cities whose names begin with a consonant and are in the Northern Hemisphere in the table
Show Hint
Count consonant-starting capitals separately for north, south and east, and separately count consonant-starting countries in the east.

- is less than the number of countries whose name begins with a consonant and are in the east of the meridian by 2
- exceeds the number of cities whose names begin with a consonant and are in the southern hemisphere by 2
- is less than the number of cities whose names begin with a consonant and are in the east of the meridian by 1
- exceeds the number of cities whose names begin with a consonant and are in the southern hemisphere by 1

The Correct Option is A
Solution and Explanation
Step 1: Classify every capital city (the question is about city names, that is, the capitals):
Vowel start: Ottawa (N) and Accra (N). The other 18 cities begin with a consonant.
Consonant and Northern Hemisphere (11): Vienna, Sofia, Phnom Penh, Teheran, Dublin, Tripoli, Kuala Lumpur, Warsaw, Riyadh, Madrid, Colombo.
Consonant and Southern Hemisphere (7): Buenos Aires, Canberra, Brasilia, Quito, Lima, Wellington, Lusaka.
Consonant and east of the meridian: all consonant cities except Madrid (\(3.45^\circ\) W), so \(18 - 1 = 17\).
Countries whose names begin with a consonant: Bulgaria, Brazil, Canada, Cambodia, Ghana, Libya, Malaysia, Peru, Poland, New Zealand, Saudi Arabia, Spain, Sri Lanka, Zambia (14). All except Spain are in the east, so 13.
Step 2: Test the options:
Option (4): \(11 - 7 = 4\), not 1. Option (2): the excess is 4, not 2.
Option (3): \(17 - 11 = 6\), not 1.
Option (1): \(13 - 11 = 2\). True.
Final Answer:
The correct option is (1): is less than the number of countries whose name begins with a consonant and are in the east of the meridian by 2.
Vowel start: Ottawa (N) and Accra (N). The other 18 cities begin with a consonant.
Consonant and Northern Hemisphere (11): Vienna, Sofia, Phnom Penh, Teheran, Dublin, Tripoli, Kuala Lumpur, Warsaw, Riyadh, Madrid, Colombo.
Consonant and Southern Hemisphere (7): Buenos Aires, Canberra, Brasilia, Quito, Lima, Wellington, Lusaka.
Consonant and east of the meridian: all consonant cities except Madrid (\(3.45^\circ\) W), so \(18 - 1 = 17\).
Countries whose names begin with a consonant: Bulgaria, Brazil, Canada, Cambodia, Ghana, Libya, Malaysia, Peru, Poland, New Zealand, Saudi Arabia, Spain, Sri Lanka, Zambia (14). All except Spain are in the east, so 13.
Step 2: Test the options:
Option (4): \(11 - 7 = 4\), not 1. Option (2): the excess is 4, not 2.
Option (3): \(17 - 11 = 6\), not 1.
Option (1): \(13 - 11 = 2\). True.
Final Answer:
The correct option is (1): is less than the number of countries whose name begins with a consonant and are in the east of the meridian by 2.

The Correct Option is A
Solution and Explanation
In the Southern Hemisphere, countries whose names start with a vowel are:
- Australia
- Ecuador
- India
The capitals whose names start with a vowel are:
- Ottawa
- Accra
- Ireland (Dublin)
Thus, the ratio is \( \frac{3}{2} \).
- Ecuador
- India
The capitals whose names start with a vowel are:
- Ottawa
- Accra
- Ireland (Dublin)
Thus, the ratio is \( \frac{3}{2} \).
