plz solve this problem​

Answer 1

Answer:

42

Explanation:

we need to assume the digits as x and y

then no. becomes 10x+y and no. obtained by reversing becomes 10y+x.

then 10x+y+10y+x=66

11x+11y=66

11(x+y)=66

x+y=6 take it as eqn.1

also given difference of the digits is 2

x-y=2 take it as eqn.2

subtract eqn.1 and eqn.2

then we get value of x and substitute the value of x as 4 in any of the equations and we will get the value of y as 2

so the required no. is 42
