SOLUTION

GIVEN

3 ducks lays 3 eggs in 3 days.

TO DETERMINE

The number of eggs will 300 ducks lay in 300 days

EVALUATION

SOLVE USING RULES OF THREE

$\sf{ : \: \: \: \: \: \: Duck \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: Day \: \: \: \: \: \: \: \: \: \: \: Number \: of \: eggs}$

$\sf{ : \: \: \: \: \: \: \: \: 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3}$

$\sf{ : \: \: \: \: \: \: \: 3 00\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 300 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ?}$

Here the number of ducks and number of eggs are in direct proportion

As number of ducks increase the number of eggs will also increase

Also the number of days and number of eggs are in direct proportion

As number of days increase the number of eggs will also increase

Hence the required number of eggs

$\displaystyle \sf{ = 3 \times \frac{300}{3} \times \frac{300}{3} }$

$\displaystyle \sf{ = 3 \times 100 \times 100 }$

$\displaystyle \sf{ = 30000}$
