Answer:

46

Step-by-step explanation:

Let number is x greater than 21 and x less than 71.

Now, according to question,

21+x=71−x

2x=50

x=25

So, required number is 21+x=21+25=46.

Alternatively,

The required number would be the average or mean of 21 and 71.

So, required number =

dimulka [17.4K]
18 is 75% of x.

75\%= \frac{75}{100}=\frac{3 \times 25}{4 \times 25}=\frac{3}{4} \\ \\
\frac{3}{4}x=18 \\
x=18 \times \frac{4}{3} \\
x=6 \times 4\\
x=24


18 is 75% of 24.
