Question

the sum of 2digit no is 9band if 27 is subtracted and no is reversed than number will be​

Answer 1

Answer:

Let us assume , x and y are the two digits of the two - digit number

Therefore , the two - digit number = 10x + y

and reversed number = 10y + x

Given : x + y = 9 ---------- (1 )

also given :

10x + y - 27 = 10y + x

9x - y = 27

x - y = 3 -------- (2)

Adding equation (1) and equation (2)

2x = 12

x = 6

Therefore , y = 9 - x = 9-6 = 3

The two - digit number = 10x + y = 10 * 6 + 3 = 63
