Question

A two digit number is 3 more than 4times thes sum of its digits if 18 is added to the number it's digits are reversed find the number​

Answer 1

Answer: 35

Step-by-step explanation:

Let ones digit of two digits number is x. and tens digit is y. Accordingly:-

10y+x= 4.(x+y) +3

10y+x=4x+4y+3. or. 3x-6y+3=0

x-2y = -1…………….(1)

10y+x+18 = 10x+y. or. 9x-9y=18.

x-y = 2…………………..(2)

Subtracting eqn (2) from (1)

-y= -3. => y=3

Putting y=3 in eqn. (1)

x-6=-1. => x= 5

Thus , the number is 10y+x= 10×3+5. = 35. AnswerLet ones digit of two digits number is x. and tens digit is y. Acordingly:-

10y+x= 4.(x+y) +3

10y+x=4x+4y+3. or. 3x-6y+3=0

x-2y = -1…………….(1)

10y+x+18 = 10x+y. or. 9x-9y=18.

x-y = 2…………………..(2)

Subtracting eqn (2) from (1)

Putting y=3 in eqn. (1)

x-6=-1. => x= 5

Thus , the number is 10y+x= 10×3+5. = 35. Answer
