Question

five times the sum of the digits of a two digit number 9 less than the number formed by reversing its digits . if four times the value of the digit at ones place is equal to half of the place value of the digit at tens place , find the number​

Answer 1

Step-by-step explanation:

Let tens place be x and ones place be y

Then,required no. = 10x+y

A/q,

5 (x+y)+9=10y+x______(1)

4y/2=x

x=2y

put the value of x in equation 1

5 (2y+y)+9=10y+2y

5 (3y)+9=12y

15y=12y-9

15y-12y=(-9)

3y=(-9)

y=(-3)

x=(-6)

we know that digits of a number are not negative

Hence,number is 36
