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?
Answer & explanation
Correct answer: option 4
60% = \(\frac{3}{5}\) & 25% = \(\frac{3}{4}\)
Amount of sugar in 700 grams of sugar cane = \(\frac{3}{5}\) × 700 = 420
ATQ ,
Let Sugar added = a
\(\frac{420 + a }{700 + a }\) = \(\frac{3}{4}\)
1680 + 4a = 2100 + 3a
a = 420
So , Amount of sugar added to make sugar percentage equals to 75% = 420 grams
