Answer 2

THANKS FOR THE QUESTION !

______________________________

GIVEN :

=> 2 NO. ARE GIVEN :

_______________________________

CONDITION :

=> 30% OF 1ST NO. IS ADDED TO 2ND ,

=> 2ND NO. INCREASES BY 1/5

_______________________________

=> LET,

1ST NO. BE ;

=> X

2ND NO. BE :

=> Y

_______________________________

30% OF 1ST NO :

=> 30 / 100 * X

______________________________

1/5 OF 2ND NO. :

=> 1/5 * Y

______________________________

TO FIND :

=> THE RATIO OF FIRST NO. WITH SECOND

______________________________

BY CONDITIONS GIVEN :

=> 30 * X / 100 + Y = Y + 1 / 5 Y

=> 30X + 100 Y / 100 = 6 / 5 Y

=> 30X + 100 Y = 100 ( 6 / 5 Y )

=> 30X + 100 Y = 600 / 5 Y

=> 30X + 100 Y = 120 Y

=> 30X = 120 Y - 100 Y

=> 30 X = 20 Y

=> X / Y = 20 / 30

=> X / Y = 2 / 3

=> X : Y = 2 : 3
