Answer 2

Value of (?) is 120.2

GIVEN:- 61%of 550 - ? % of 250 = 35

TO FIND:- (?)

SOLUTION:-

• Percentage (%) is the fraction of 100
• Of imply multiplication

Let (?) be x

61%of 550 - ? % of 250 = 35

First, we'll solve 61%of 550

$61\% \: of \: 550 \\ = \frac{61}{100} \times 550 \\ = \frac{33550}{100} \\ = 335.5$

Secondly, we'll solve x % of 250 = 35

$x\% \: of \: 250 \\ = \frac{x}{100} \times 250 \\ = \frac{250x}{100} \\ = 2.5x$

Now,

According to the question,

$335.5 - 2.5x = 35 \\ 335.5 - 35 = 2.5x \\ 2.5x = 300.5 \\ x = \frac{300.5}{2.5} \\ x = 120.2$

Hence, value of (?) is 120.2
