Answer 2

Step-by-step explanation:

LET THE SUM OF MONEY YOU HAVE = x

according to question,

12% of x = 42

which can be written as

$\frac{12}{100} \times x = 42 \\ \frac{12x}{100} = 42 \: \: \: \: \: \\ 12x = 42 \times 100 \\ 12x = 4200 \\ x = \frac{4200}{12} \\ x = 350$

SO we got that the sum of money you have (x) is equal to 350.

Now we have to find 20% of it,

$\frac{20}{100} \times 350 \\ = \frac{350}{5} = 70$

It means 20% of the sum of money you have is 70.
