Question

Five times the sum of digit of two number is 9 less than the number formed by reversing its digit. If four times thevalue of the digit at ones place is equal to the half of the valaue of the digit at ten place. Find the number

Answer 1

Answer:

the answer 36

Step-by-step explanation:

Let the two digits number is xy.

Here, Unit Digit = y and Tenth Digit = x

Given x + y = 9 ——————— ( 1 )

and y = x/2

=> 2 y = x ——————— ( 2 )

Substituting value of “ x “ in equation ( 1 ), we have

2 y + y = 9

=> 3 y = 9

=> y = 9 / 3

=> y = 3

=> x = 2 y

Substituting value of “ y “ in equation ( 2 ), we have

=> x = 2 y

=> x = 2 ( 3 )

=> x = 6

Therefore, Required number = 36
