Question

the digit in the unit place of a two digit number is 4 times the digits in the tens place the number obtained by reversing the number by 54 find the number

with step by step in attachment

Answer 1

Answer:

Let one's digit be 4x. Then, ten's digit =x.

Number =10x+4x=14x ....(1)

Number obtained by reversing the digits =40x+x=41x

According to the given condition,

41x−14x=54

27x=54

x=2

Putting the value of x in (1) , we get

Number =14×2=28

Hence, 28 is the required number.

OR

According to question, if the digits are reversed and the original number is subtracted from the new number, the difference is 54. Hence the desired number is 14a = 14(2) = 28 Required number is 28.
