Answer: The value of whole is 120.

Step-by-step explanation:

Since we have given that

84 is 70% of the whole.

Let the whole be 'x'.

According to question, it becomes,

84=\dfrac{70}{100}\times x\\\\84=0.7\times x\\\\\dfrac{84}{0.7}=x\\\\120=x

So, we have use the proportion i.e. \dfrac{84}{70\%}=\dfrac{84}{0.7} to determine the value of whole.

Hence, the value of whole is 120.
