Answer 1

Step-by-step explanation:

Hola!

From the given data

We can get the equation,

n. n. n. 7

--- + --- + --- + --- = n

2. 4. 5. 1

Make L.C.M. to all factors,

10n+4n+5n+7×20

------------------------------. = n

20

19n+140

--------------. = n

20

19n+140= 20n

20n-19n=140

Therefore,

n=140
