Question

plz solve this plzzzzz... its very urgent​

Answer 1

Answer:

let the required number be ab.

sum of digits=a+b....(1)

10 a+b =4 (a+b)

9 a+ 18 = 9 b

a+2=b

10 a+a+2=4(a+a+2)

11a+2=8a+8

3a=6

a=3

a+2=5

ab=35

Answer 2

Answer:

35

Step-by-step explanation:

let digits be x, y

10x+y=3+4x+4y

=>6x-3y=3

=>2x-y=1.................(1)

10x+y+18=10y+x

=>9y-9x=18

=>y-x=2

=>y=x+2.................(2)

we have

replacing (2) in (1)

2x-(x+2)=1

x-2=1

x=3

replacing x=3 in (2)

y=5

number = 35
