Question

find number when increased by 30% becomes 39​

Answer 1

Answer:

Let the number be "x"  

Number is increased by 30%...  

Therefore, Final number(answer) is x+(30/100)x  

Therefore,  

x+(30x/100) = 39

130x/100 = 39

130x = 3900

x = 3900/130  

x = 390/13  

x = 30.  

So, your original number "x" is 30

Answer 2

let the number be x.

then according to the question,

x+30% of x=39

x + x * 30/100= 39

x(1+(30/100)) = 39

x (100+30)/100 =39

x (130) = 39*100

x = (39*100)/130

x= 30

Ans. The number is 30.
