Question

Find the number which when increased by 30% becomes 39.( with statements) ​

Answer 1

Answer:

let the number be x

According to question, x + 30x/100 = 39

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

==> 130x/100 = 39

==> 13x/10 = 39

==> 13x = 39 × 10

==> 13x = 390

==> x = 390/13

==> x = 30

∴ The number is 30.

Answer 2

let the number be x

A. T. Q

x+30%= 39

x+30/100 = 39

x+3/10 = 39

x= 39-3/10

x= (390-3)/10

x = 387/10

x = 38.7
