hey mate
here is your answer
if 7^n be the number given
where n is given
then
we know that 7^1=7
7^2=49
7^3=343
7^4=2401
so if n is divided by 7 completely then remainder=0
the number ends with 7
similarly it ends with 9 if remainder is 1
and it ends with 3 when remainder is 2
and it ends with 1 when remainder is 3
so in this case n=25
so the number must end with 9
so 9-7=2 is the correct answer.
