600 g of Jaggery Syrup has 40% jaggery in it, how much jaggery should be added to make it 50% in the syrup?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 120 gm
$\text{Initial jaggery} = 40\% \text{ of } 600 = 240 \text{ g}$
$\text{Let } x \text{ g jaggery be added}$
$\text{New jaggery} = 240 + x$
$\text{Total mixture} = 600 + x$
$\frac{240 + x}{600 + x} = \frac{1}{2}$
$2(240 + x) = 600 + x$
$480 + 2x = 600 + x$
$x = 120$
The jaggery to be added is $120$ g.
