• A. The ratio of length of snake to crocodile is 5 : 1
• B. The ratio of length of snake to crocodile is 1 : 20
• C. Crocodile is 10 times longer than the snake.
• D. Crocodile is 15 times longer than the snake.

Answer 1

The correct option is B

The ratio of length of snake to crocodile is 1 : 20

Ratio is a method of comparing two quantities having the same unit,

2 m = 200 cm

Hence, the ratio of the length of the snake to crocodile would be
$\frac{10}{200}=\frac{1}{20}=1:20$
