• A. ₹50
• B. ₹25
• C. ₹75
• D. ₹100

Answer 1

The correct option is B ₹25

$1l$ of juice $=₹100$
$250ml$ of juice $=?$

We know that, $1l=1000ml$
So now, $1000ml$ of juice $=₹100$

$250ml$ is 1 out of 4 parts of $1000ml$, i.e., $\frac{1}{4}$ of $1000ml.$

Similary, 1 out of 4 parts of ₹100,
i.e.,$\frac{1}{4}$ of ₹100 is ₹25.

$\therefore$ Radhika needs ₹25 to buy ₹250 ml of juice.
