Question

answer no 3 plzzz fast

Answer 1

Let the digits be x, y
Let x be at ten's place and y be at unit's
Then, the number =10x +y-------(1)
First condition:
10x +y=4(x+y)+3
10x+y-4x-4y=3
6x-3y=3
2x-y=1-------(2)
Second condition
(10x+y)+18=10y+x
10y+x-10x-y=18
9y-9x=18
y-x=2-----(3)
Adding 2 and 3
x=3
Putting the value of x in 3
y=5
Hence the number =35
