Given :

• Ramesh needs x gram of sugar to make 150 g of sugar solution with 20% (w/w)

To Find :

• value of x and y

Solution :

$\huge\sf\rightarrowtail$ Given that Ramesh wanted X gram of sugar to make 150 gram of sugar solution .

So ,

$\sf\huge\implies$$\frac{x}{150}$ × 100

$\sf\huge\implies$ 20

$\sf\huge\implies$ x = 20 × $\frac{15}{10}$

$\sf\huge\implies$ 30 g

Therefore, value of x is equals to 30g.

$\star$ Again Rohan added y gram of water to reduce concentration to 15 % (w/w)

So ,

$\sf\huge\implies$ $\frac{30}{15 + y}$ = $\frac{15}{100}$

$\sf\huge\implies$ $\frac{15}{150}$ + (y)

$\sf\huge\implies$ 30 × 100

$\sf\huge\implies$ 150 + y = 200

$\sf\huge\implies$ y = 50

Hence , value of y = 50 g
