- A solution of ‘THANDA SHARBAT’ has 15% sugar.
Question 1:
A solution of ‘THANDA SHARBAT’ has 15% sugar. Another solution has 5% sugar. How many liters’ of the second solution must be added to the 20L of first solution to make a solution of 10 % sugar? A. 10 L
B. 5 L
C. 15 L
D. 20 L
Feedback Let required amount of second solution to be added = a L
Then 15 × 20 + 5a / 20 + a= 10
⇒ 300 + 5a = 200 + 10a
⇒ 5a = 100
⇒ a = 20
Then 15 × 20 + 5a / 20 + a= 10
⇒ 300 + 5a = 200 + 10a
⇒ 5a = 100
⇒ a = 20
