1.	The ratio of the present ages of Amrit and Abhi is 4 ∶ 5. Kunal, who is 5 years younger to Amrit celebrated his 12th birthday 3 years ago. Find the difference in the ages of Kunal and Abhi.1. 6 years2. 8 years3. 10 years4. None
Answer» Correct Answer - Option 3 : 10 years Given: Ratio of present ages of Amrit and Abhi = 4 ∶ 5 Amrit – Kunal = 5 years Kunal’s age, 3 years ago = 12 years Concept used: To convert any ratio to an exact value, we should have to multiply any constant value The present age of Kunal = 15 years (12 +3) ∴ Age of Amrit = 15 + 5 = 20 Now, let present ages of Amrit and Abhi be 4x and 5x respectively ∴ 4x = 20 ∴ x = 5 Present age of Abhi = 5 × 5 = 25 Therefore, the difference of age of Abhi and Kunal = 25 – 15 = 10 years

The ratio of the present ages of Amrit and Abhi is 4 ∶ 5. Kunal, who is 5 years younger to Amrit celebrated his 12th birthday 3 years ago. Find the difference in the ages of Kunal and Abhi.1. 6 years2. 8 years3. 10 years4. None

Answer» Correct Answer - Option 3 : 10 years

Given:

Ratio of present ages of Amrit and Abhi = 4 ∶ 5

Amrit – Kunal = 5 years

Kunal’s age, 3 years ago = 12 years

Concept used:

To convert any ratio to an exact value, we should have to multiply any constant value

The present age of Kunal = 15 years (12 +3)

∴ Age of Amrit = 15 + 5 = 20

Now, let present ages of Amrit and Abhi be 4x and 5x respectively

∴ 4x = 20

∴ x = 5

Present age of Abhi = 5 × 5 = 25

Therefore, the difference of age of Abhi and Kunal = 25 – 15 = 10 years
