Question

300 grams of sugar solution has 40% sugar in it. How much sugar should be added to make it 50% in the solution?

• A. 10 gms
• B. 40 gms
• C. 60 gms
• D. 80 gms

Answer 1

The correct option is C 60 gms

$Sugar=(\frac{40}{100}\times 300)gms=120gms,$
water = 180 gms.
Let x gm sugar may be added.

$Then,\frac{120+x}{300+x}\times 100=50\Rightarrow 240+2x$

$=300+x\Rightarrow x=60$
