Answer 1

Answer: The value of whole is 120.

Explanation:

Since we have given that

84 is 70% of the whole.

Let the whole be 'x'.

According to question, it becomes,

`84=(70)/(100)* x\\\\84=0.7* x\\\\(84)/(0.7)=x\\\\120=x`

So, we have use the proportion i.e.
`(84)/(70\%)=(84)/(0.7)` to determine the value of whole.

Hence, the value of whole is 120.
