Answer 1

Given :- A milkman has a 45 litre of milk in a drum and a 500ml milk measuring cup.

To find :- Tell how many times he has to fill the cup to empty the drum.?

Solution :-

we know that,

SOLUTION

GIVEN

A milkman has a 45 litre of milk in a drum and a 500ml milk measuring cup.

TO DETERMINE

The number of times to fill the cup to empty the drum.

EVALUATION

Here it is given that a milkman has a 45 litre of milk in a drum and a 500 ml milk measuring cup.

Now 1 litre = 1000 ml

45 litre

= 45 × 1000 ml

= 45000 ml

So total amount of milk = 45000 ml

Amount of milk in each cup = 500 ml

So the required number of times to fill the cup to empty the drum

$\displaystyle \sf{ = \frac{Total \: amount \: of \: milk \: in \: the \: drum}{Amount \: of \: milk \: in \: each \: cup }} \:$

$\displaystyle \sf{ = \frac{45000}{500} }$

$\displaystyle \sf{ =90}$
