let the no. be x
a/q
x+ 30% of x = 39
=>x + 30x/100 = 39
=>x + 3x/10 =39
=>10x + 3x = 39
_______
10
=> 13x/10 = 39
=> 13x = 390
=> x = 390/13
=> x = 30

hence, the required no. is 30

Answer 2

Let the no be x
A/q
X + 30% of x = 39
X+ 30/100 * x = 39
X + 3x/10 = 39
X + 3x = 39*10
4x = 390
X = 390/4
X = 97.5

The number is 97.5
