Correct Answer - Option 1 : 240 ml
Given:
Wine and soda are in the ratio of 7 ∶ 2.
The quantity of wine is 560 ml.
Calculations:
Let the quantity of wine and soda be 7x and 2x respectively.
The quantity of wine is 560ml = 7x
⇒ x = 560/7 = 80
So quantity of soda = 2 × 80 = 160 ml
Let the amount of wine added be y
According to the question,
(560 + y)/160 = 5/1
⇒ 560 + y = 800
⇒ y = 800 - 560 = 240 ml
∴ The quantity of wine to be added to it to make the ratio 5 ∶ 1 is 240 ml
