Question

If n erasers have a weight of 80 grams, what is the total weight of 50 erasers?

Answer 1

weight of 50 erasers is
`(80)/(n)* 50` g

Explanation:

Given that n erasers have a weight of 80 grams,

we have to find total weight of 50 erasers

Now, weight of n erasers=80 g

∴ weight of 1 eraser =
`(80)/(n)` g

⇒ weight of 50 erasers =
`(80)/(n)* 50` g

Hence, weight of 50 erasers is
`(80)/(n)* 50` g

Answer 2

`The\ weight\ of\ the\ 50\ erasers\ be\ (4000)/(n)\ grams.`

Explanation:

As given

if n erasers have a weight of 80 grams .

I.e

n erasera = 80 grams.

1 erasers weight .

`1\ erasers\ weight = (80)/(n)`

Now find out the weight of the 50 erasers.

`Weight\ of\ 50\ erasers = (50* 80)/(n)\ grams`

Simplify the above

`Weight\ of\ 50\ erasers = (4000)/(n)\ grams`

`Therefore\ the\ weight\ of\ the\ 50\ erasers\ be\ (4000)/(n)\ grams.`
