• A. ₹10
• B. ₹25
• C. ₹50
• D. ₹75

Answer 1

The correct option is B ₹25

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

We know that, $1l=1000ml$.
So now, cost of $1000ml$ 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.

$\therefore$The cost of 250 ml of juice is ₹ 25.
