Question

and tel me how can we solve these types 

Answer 1

A number increased 37 ½% gives 33. The number is?

Give a variable name (usually a letter, maybe x) to the number. 

Now it reads:

x increased by 37 1/2% ( of x) gives 33, or

x + (37 1/2 % * x) = 33

x + (37.5%x) = 33

1x + (.375x) = 33

1.375x = 33

Divide both sides by 1.375

x = 24
