the sum of the digits of a two digit number is 6 if tje digits are reversed the new number will be 36 grater than the original number find the number
Answers
Answer:
15,36
Step-by-step explanation:
x and y are two digits of a number
number = n
Sum of the digits
x+y=6.....................(1)
When x is ten and y is unit
10x+y=n.............(2)
When the digits are reversed, the new number is 36 more than the original number
Now y is ten and x is unit
10y+x=n+36.............(3)
Subtract (2) from (3)
10y+x=n+36.............(3)
-10x-y=-n.............(2)
-------------------------
-9x+9y=36
9(y-x)=36
9(y-x)/9=36/9
y-x=4...................(4)
Add (1) and (4)
y-x=4...................(4)
x+y=6.....................(1)
-----------------------------
2y=10
2y/2=10/2
y=5
Put the value of y in (1)
x+5=6.....................(1)
x=6-5
x=1
Number = 15
When the digits are reversed = 51 (15+36=51)
hope it is helpful
have a nice day
Answer:
15
Step-by-step explanation:
let no is xy
x+y=6reverseno is yx
10y+X =10x+y+36
x+10y-10x-y=36
-9x+9y=36
-x+y=4
x+y=6
2y=10
y=5
x=6-y
x=6-5=1
no=15
