Question

a number increased by 45/2% gives 98 . find the number​

Answer 1

Step-by-step explanation:

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
