Step-by-step explanation:

Answer 2

The ratio between the numbers a and b is 4 : 5

Step-by-step explanation:

Statement I : 50% of a is 25% of 80.

50% of a = 25% x 80

=> 2a = 80

=> a = $\frac{80}{2}$ = 40

Statement II: 20% of b is 10% of 100.

20% of b = 10% of 100

=> 2b = 100

=> b = $\frac{100}{2}$ = 50.

Ratio between a and b = $\frac{40}{50} = \frac{4}{5}$

Hence, the ratio between the numbers a and b is 4 : 5
