Question

the sum of the digits of a two digit number is 9 the number is 6 times the unitd digit.find the number

Answer 1

Let the unit place be x
The tens place be y

ATP

x+y=9.........i
10y+x=6x.....ii

Now finding the value of x from i
x+y=9
x=9-y

Now Substituting value of x in ii

10y+x=6x
10y+9-y=6(9-y)
9y+9=54-6y
9y+6y=54-9
15y=45
y=45/15
y=3

Now putting the value of y in i

x+y=9
x+3=9
x=9-3
x=6

Now the no. Is
10y+x
10.3+6
36
