Question

sum of two digit of a two digit number is 10. the number obtained by reversing the digit is 36 greater than the original number find the number​

Answer 1

Answer:

37

Step-by-step explanation:

unit= x

tens= y

original number = 10y+x

given sum of two digits is 10

x+y=10 (1)

now number obtained by reversing the number is 36 greater,

10y+x+36=10x+y

= x-y=4 (2)

in solving 1 and two by eliminating method

x=7

y=3

thus no = 37.
