Answer 2

Answer:

Cost of 4 pen is 140rs

Step-by-step explanation:

Given that

cost of 6 pens is 210

To find

cost of 4 pen

Solution

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

$cost \: of \: 1 \: pen = \frac{210}{6}$

by divide we get

$cost \: of \: 1 \: pen = 35rs$

now

$cost \: of \: 4 \: pen = 4 \times 35$

by multiplication we get

$cost \: of \: 4 \: pens = 140rs$
