Question

In the given figure the areas of diferent continents are given:
What is the ratio of the areas of
a. Africa to Europe
b. Australia to Asia
c. Antarctica to combined area of North America and South America.

• A. (a) 8:89 (b) 2:25 (c) 13:45
• B. (a) 6:7 (b) 5:6 (c) 8:34
• C. (a) 13:5 (b) 2:11 (c) 13:35
• D. None of these

Answer 1

The correct option is C (a) 13:5 (b) 2:11 (c) 13:35

(a) Area of Africa =26 sq. units
Area of Europe =10 sq. units
$RatioofareasofAfricaandEurope=\frac{AreaofAfrica}{AreaofEurope}$
$=\frac{26}{10}=\frac{13}{5}$ or $13:5$
Hence, area of Africa to Europe is in the ratio 13 : 5.
(b) Area of Australia = 8 sq. units
Area of Asia =44 sq. units
$Therequiredratio=\frac{AreaofAustralia}{AreaofAsia}$
$=\frac{8}{44}=\frac{2}{11}$ or $2:11$
Hence, ratio of the area of Australia to Asia is 2 : 11.
(c) Area of Antarctica =13 sq. units
Area of North America =17 sq. units
Area of South America =18 sq. units
Combined area of North and South America
= 17 + 18 = 35 sq.units
$Therequiredratio=\frac{AreaofAntarctica}{CombinedareaofNorthandSouthAmerica}$
$=\frac{13}{35}$ or $13:35$
Hence, ratio of area of Antarctica to combined area of North and South America is 13 : 35.
