  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.

  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

    Hope it helps you
