Answer 2

Step-by-step explanation:

1) let the two digit number be 10x+y

gn : two digit number is four times the sum of its digits .

10x+y = 4(x+y)

10x+y = 4x+4y

6x - 3y = 0

2x - y = 0 ( dividing both sides by 3)

2x= y

gn : it is equal to three times product of its digits

10x+y = 3xy

10x+2x = 3x(2x)

12x = 6x²

x= 2

Since y = 2x , y = 4

Hence two digit number is 24

2) Let the fraction be x/y

1st condition : x+2/y+2 = 9/11

11x + 22 = 9y+ 18

11x - 9y = -4 (equation1)

2nd condition : x+3/y+3 = 5/6

6x+18 = 5y+15

6x-5y = -3 (equation2)

Solve both equations you get ,

x= 7 and y= 9

Fraction is 7/9
