9. Let the coefficient be x.
One no. = x
Another no. = 3x
Now, Difference = 32
So, 3x -x = 32
i.e. x = 16
Integers are 16 and 48.
10.Let the numerator be x.
Denominator = x+5
According to the question,
(x+2)/(x+5+2) = 4/5
i.e. x= 18
Fraction will be 18/23.
11. This question is same as 10. Try to solve.
12. Let the digits be x and y .
x+y = 8 ,which is given
No. will be 10x+y and after interchanging the digits no. will be 10y+x.
Now,
10y+x -(10x+y)= 18.
i.e. y-x = 2.
By solving both the equations you will get
x= 3 and y = 5.
Hence, no. will be 35.
