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}}
