Question

A number consists of two digits whose Sum is 9.i
27 is sub tracted from the number digits are reversed
find the number
1​

Answer 1

Answer:

63

Step-by-step explanation:

Leth the number be 10x+y here x is tens place and y is ones place

when reversed=10y+x

by question x+y=9⇔equation 1

and 10x+y-27=10y+x

9x=9y+27

x-y=3

from 1 ⇒x+y=9

2x=12

x=6 then y=9-x=9-6=3

therefore original number (10)6+3=60+3=63
