Question

If in a zoo, out of 150 birds, 45 birds are migratory and $\frac{3}{5}$ of the total birds are of Indian origin, then which kind of birds are more in number?

• A. Migratory birds
• B. Indian birds
• C. Both are same in number
• D. Data insufficient

Answer 1

The correct option is B

Indian birds

Total number of birds = 150

Number of migratory birds = 45

$\Rightarrow$ Fraction representing migratory birds = $\frac{45}{150}=\frac{3}{10}$

Fraction representing birds of Indian origin = $\frac{3}{5}=\frac{3\times 2}{5\times 2}=\frac{6}{10}$

We can see that $\frac{6}{10}$ and $\frac{3}{10}$ are like fractions as their denominators are same.

Since 6 > 3,

$\frac{6}{10}>\frac{3}{10}$

Therefore, birds of Indian origin are more in number.
