Answer 2

Given: The cost of $25$pens is$225Rs.$

We have to find how many such pens can buy for$810Rs.$

We are solving in the following way:

We have,

The cost of $25$pens is$225Rs.$

So, the cost of the one pen will be:

$=>\frac{225}{25} \\\\=> 9$

Hence, the cost of one pen is$9Rs.$

So, the number of pens can buy for Rs$810$ will be:

$=>\frac{810}{9} \\\\=>90$

Hence, such $90$pens can buy for Rs$810$.
