700 grams of cane sugar solution has 60% of sugar in it. How much sugar should be added to make it 75% in the solution?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 420 gm
Amount of sugar in 700 gm = 60% of 700 = 420 gm
Let us suppose that x gm of sugar is added to 700 gm of sugarcane to make the amount of sugar 75%
⇒ (700 + x) × (3/4) = 420 + x
⇒ 2100 + 3x = 4x + 1680
⇒ x = 420 gm
