Answer 2

Given-

The cost of 3 pen is Rs. 60

We have to find out the cost of 10 pen .

As per given information,

The cost of 3 pen

$= 60$

So,

The cost of one pen

The cost of one pen

$= 60 \div 3 = 20$

The cost of one pen is Rs 20.

The cost of 10 pen

$= the \: cost \: of \: one \: pen \times 10 \: number \: of \: pen$

The cost of 10 pen
