Answer 1

Step-by-step explanation:

(a) 25% of x is 40

$=>\frac{25}{100}(x)=40$

$=>x=\frac{(40)(100)}{25}$

=> x = 160

(b) x% of 17.5 is 350

$=>\frac{x}{100}(350)=17.5$

$=>x=\frac{17.5(100)}{350}$

=> x = 5

(c) x% of 1800 is 90

$=>\frac{x}{100}(1800)=90$

$=> x= \frac{90(100)}{1800}$

=> x = 5

(d) 30% of x is 21

$=>\frac{30}{100} (x)=21$

$=>x=\frac{21(100)}{30}$

=> x = 70
