Answer 1

Answer:

Step-by-step explanation:

let the 2digit number be ab

10a+b=4a+4b or 6a=3b or b=2a

b=a²-8 or a²+2a =8 or a²+2a+1=9 or (a+1)²=3²

since a is positive, a+1=3 or a=2

b=4

the number is 24

Answer 2

Answer:

28

Step-by-step explanation:

Let's take number as 10x+y

As per question,

y=4x, and

x+y=10

So, x+4x=10

5x=10

x=2

y=2×4=8

So, number is 10x+y=10×2+8=28
