here is your solution mate
Step-by-step explanation:
let the 3 digit number be a-d,a,a+b
let the 3 digit number be a-d,a,a+bthe it is given that it's sum is 12
(a-d)+(a)+(a+d)=12
a-d+a+a+d=12
3a=12
a=12/3
a=4.
now if the digits are reversed,
100(a+d)+ 10a+(a-d)=100(a-d)+10a+(a+d)-396
putting the value of a =4 the equation will be
400+100d+40+4-d=400-100d+40+4+d-396
99d=-99d-396
99d+99d=-396
198d=-396
d=-396/198
d=-2
with a=4 and d=-2
the number is (a-d )(a) (a+d)
[4-(-2)](4)[(4+(-2)]
[4-(-2)](4)[(4+(-2)]642 ans
