Given that

cost of 6 pens is 90

To find

cost of 10 pens

Solution

As cost of 6 pens given from this we can determine cost of 1 pen as

$cost \: of \: 1 \: pen = \frac{90}{6}$

by divide we get

$cost \: of \: 1 \: pen = 15rs$

now

$cost \: of \: 10 \: pen = 10 \times 15$

by multiplication we get

$cost \: of \: 10 \: pens = 150rs$

hence cost of 10 pens is 120rs is false.
