Correct Answer - Option 3 : 5 liters
Given:
Total amount of juice = 35 liters
The ratio of A and B = 4 ∶ 3
Calculation:
Let the amount of A and B in juice be 4x and 3x
Then, according to the question, we have
4x + 3x = 35 liters
⇒ 7x = 35 liters
⇒ x = 5 liters
So, the amount of A = 4x = 4 × 5 = 20 liters
And, amount of B = 3x = 3 × 5 = 15 kg
Difference of A and B = (20 - 15) liters = 5 liters
So, if we add 5 liters of B then we get the ratio 1 ∶ 1
∴ The required amount of mango is 5 liters.
