Answer 1

Answer:

9) 45 is the correct answer

Answer 2

Answer:

8. 20

9. 180

Step-by-step explanation:

$\bold{8.}$ If x% of 250 + 25% of 68 = 67, then the value of x is .......

According to Question ,

$\implies \: \sf{x\% \: of \: 250 \: + \: 25\% \: of \: 68 \: = \: 67}$

$\implies \:\sf{(\frac{x}{100} * 250) \: + \: (\frac{25}{100}*68) \: = 67 }$

$\implies \: \sf{\frac{25x}{10} \: + \: (\frac{1}{4}*68) \: = \: 67}$

$\implies \: \sf{\frac{5x}{2} \: + \: \frac{68}{4} \: = \: 67}$

$\implies \: \sf{\frac{5x}{2} \: + \: 17 \: = 67}$

$\implies \: \sf{\frac{5x}{2} \: = 67 - 17}$

$\implies \: \sf{\frac{5x}{2} \: = \: 50}$

$\implies \: \sf{x \: = \: 50 * \frac{2}{5} }$

$\boxed{\bold{x \: = \: 20}}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\bold{9.}$ 5% of a number is 9. The number is .....

Let the number of x.

According to the Question,

5% of x = 9

⇒ ${\frac{5}{100} * x}$ = 9

⇒ x = 9 ${* \: \frac{100}{5}}$

⇒ x = 180

$\boxed{\bold{x \: = \: 180}}$
