Question

the sum of the digits of a two digit number is 10. if 18 be subtracted from it the digits in the resulting number will be equal. the number is?​

Answer 1

Answer:

The number is 73

Step-by-step explanation:

Let the number be 10x + y

Given x + y = 10 ,

10x + y - 18 = A two digit number whose digits are equal

10x + y = A two digit number + 18

Consider, 11 + 18 = 29 = 2 + 9 = 11

22 + 18 = 40 = 4 + 0 = 4

33 + 18 = 51 = 5 + 1 = 6

44 + 18 = 62 = 6 + 2 = 8

55 + 18 = 73 = 7 + 3 = 10 ✓

Hence, the two digit number is 73
