Question

The digit in the tens place of a 2-digit number is three times of that of the ones place digit.If the digits are reversed the new number will be 36 less than the original number. Find the number

Answer 1

Answer:

62

Step-by-step explanation:

The 1's digit is x

the 10's digit is 3x

the number is (3x*10)+x=31x

the reverse number is (x*10)+3x=13x

according to the question, 31x-36=13x

or,

18x = 36

or,

x=2

the number is 31x so, it is 62
