Question

A number has two digits. The digit at unit’s place is four times the digit at tens
place. If 54 is added to the number, the digits are reversed. Find the number.

Answer 1

Answer:

28

Step-by-step explanation:

units place digit is 4x

tens place digit is x

Original number is 10x+4(x)=14x

Reversed number is 10(4x)+x=41x

now,

• 14x+54=41x
• 54=27x
• x=2
