Question

The difference between a number divided by 3 and 4 is 20.

Answer 1

$*\\ x-\ number\\\\ \frac{x}{3}-4=20\ \ \ \ |Multiply\ by\ 3\\\\ x-12=20\ \ \ \ |Add\ 12\\\\ x=32\\\\Number\ is\ equal\ to\ 32.$

Answer 2

Let, the number be "a"

Now, according to the question,
$\frac{a}{3} - 4=20$

$\frac{a-12}{3} =20$

$a-12 =20*3$

$a-12=60$

$a = 60 + 12$

$a = 72$


So, the number is 72
