Question

In a two digit number, digit in units place is twice the digit in tens place. If 27 is added to it, digits are reversed. Find the number. (God this question was really tough. Would be great if someone could help. Over and Out)

Answer 1

Answer:

36

Explaination:

Let digit in tens place be x

So,digit in units place=2x

Hence,original no= 10x+2x=12x

Reversed no=20x+x=21x

According to the question,

12x+27=21x

12x-21x=-27

-9x=-27

x=-27/-9

x=3

So, original no.=12*3=36
