Question

please solve it please

Answer 1

Solution:

Let the two digit no. be 10x+y

Now as per the question:

x + y = 11 .....(1)

Again,

10x + y + 4= 10y + x - 41

or 4+41= 10y -y +x - 10x

or 45 = 9y - 9x

or 45/9 = y - x

or y - x = 5 ....(2)

Solving equations (1) and (2),we get

x +y + y - x = 16

or 2y = 16

or y = 16/2 =8

Now put y=8 in eq.(1)

X+8 =11

or x= 11 - 8= 3

Therefore, the no. is 38. Ans.

Hope it helps you!
