Answer:
87.50
Step-by-step explanation:
Let x be the required number,
Then 20% of x = [tex]\frac{20x}{100}[/tex] = 0.20x
According to the question,
20% of x = 35
[tex]\implies 0.20x = 35[/tex]
Divide both sides by 0.20
[tex]x=175[/tex]
Thus, the required number is 175,
Now, 50% of 175 = [tex]\frac{50\times 175}{100}[/tex]
[tex]=\frac{8750}{100}[/tex]
[tex]=87.50[/tex]
