Answer 2

VALUE OF x = 350

GIVEN:- 42% of 4000=x% of 480

TO FIND:- Value of x

SOLUTION:-

• The meaning of Percentage (℅) is "per 100" and implies a piece of a total amount.
• In mathematics, a percentage is a number or ratio which is expressed as a fraction of 100.
• In mathematics, of imply multiplication

Therefore,

$42\% = \frac{42}{100} \: \: x\% = \frac{x}{100}$

According to the question,

$42\% of \: 4000 = x\% \: of \: 480$

$\frac{42}{100} \times 4000 = \frac{x}{100} \times 480 \\ 42 \times 40 = \frac{48x}{10 \\ } \\ 42 \times 40 \times 10 = 48x \\ 16800 = 48x \\ x = \frac{16800}{48} \\ x = 350$

HENCE, VALUE OF x = 350
