Question

Write all the 2 digit number which when added to 27 gets reversed.
By some easy method

Answer 1

Answer:

Let the number is such that it has x in tens place and y in ones place.

So the number is = (10x + y)

So 27+(10x+y)=10y+x [Reversed]

So 9x + 27 = 9y => x+3=y

So x can't be 0 as it is two digit number so if :

• x=1,y=4
• x=2,y=5
• x=3,y=6
• x=4,y=7
• x=5,y=8
• x=6,y=9
• x=7,y=10 (not possible as y is a single digit number)

So the numbers are : 14,25,36,47,58,69.
