Correct Answer - Option 3 : 2 ∶ 5
Given:
75% of a number is equal to the 30% of another number
Calculations:
Let the number be y and z
According to the question, we have
75% of y = 30% of z
⇒ (75/100) × y = (30/100) × z
⇒ 3y/4 = 3z/10
⇒ y/z = (3 × 4)/(3 × 10)
⇒ y/z = 2/5
∴ The ratio of y and z is 2 ∶ 5.
