Answer 2

Answer:

Step-by-step explanation:

1) Let the number be = x

 Increased the number by 2 = x+2

 Three times the number = 3(x+2)

 Four added to the number = 3(x+2)+4

  Therefor -:

  3x+6+4 =28

  3x+10 = 28

  x =6

2) Let the present age of Gopi be =x

   16 years from now, the age will be = x+16 =Five times the present age= 5x

   Therefor-:

   x+16 = 5x

   x = 4

   Hence the present age of Gopi is = 4 years

3) 2x-3/3x-5 = 1/2

    4x- 6 = 3x-5

    x = 1

4) let the bigger part be = x

   smaller part = 2x/7

  Therefor -:

  x+2x+7 = 54

  x = 42

  Hence the bigger part is 42 and the smaller part is 12.
