Answer:
This is a very simple question.....
Let the no. be 10x + y
According to question
x=3y..............(1)
by interchanging the digits we get
the no. as 10y + x
According to question
10x + y + 10y + x = 88
11x + 11y = 88
11(x + y) = 88
x + y = 8............(2)
Putting value of equation 1 in equation 2 we get
3y + y = 8
4y = 8
y = 2
Now putting value of y in equation 2 we get
x + 2 = 8
x = 8 - 2
x = 6
Hence x = 2
y = 6
Hope it helps.....Priyanshi
