Question
Out of a 200-litre solution of juice and soda, the ratio of
juice to soda is 1:4. How many litres of juice should be added to make the new ratio 3:8?Solution
ATQ,
Juice = (1/5) × 200 = 40 litres
Soda = (4/5) × 200 = 160 litres
Let the amount of juice added = x litres
Then, (40 + x) : 160 = 3 : 8
So, 40 + x = (3/8) × 160 = 60
x = 60 - 40 = 20 litres
