Step-by-step explanation:
let the 2 digit no. =10a+b
a+b=10. (given)........(eq1)
no. interchanging its digit=10b+a
according to question
(10a+b)-36=10b+a
10a+b-10b-a=36
9a-9b=36
9(a-b)=36
a-b=4.....(eq2)
add eq1 and eq2 we get
2a=14
a=7 put in eq1
b=3
the the 2 digit no. =10a+b=10(7)+3=73
no. interchanging its digit=10b+a=37
