Question

3. A rat is trying to drink milk from a jar by putting pebbles inside it . Given that volume of the jar is 200 ml. If the rat requires 10 similar pebbles to get the milk till the brim of jar, Write down an equation to find the volume of each pebble corresponding to volume of milk available in the jar? Assume that the volume of each pebble is p and volume of milk in the jar is m.

Answer 1

Answer:

$p=\frac{200-m}{10}$

Step-by-step explanation:

Given:

The volume of the jar is 200ml.

The rat needs 10 pebbles to get the milk to the brim of jar.

Volume of each pebble is P.

Volume of milk in the jar is m.

Calculation:

Since 10 pebbles are needed to bring the milk to the brim of jar,

Therefore volume of the jar is equal to the summation of volume of 10 pebbles and volume of milk.

Thus,

$10P+m=200$

$10P=200-m\\p=\frac{200-m}{10}$

Thus we get the required equation.
