​

Answer 1

Answer:

answer is option (A) 82

Step-by-step explanation:

let the unit digit of number = x

and tens digit of number= y

A.T.Q

y - x + 4= x + y

x + y - y + x = 4

2x = 4

x = 4/2

x = 2

and. product of digit = 16

xy = 16

put x = 2

2y = 16

y = 16/2

y = 8

then number is in form 10y + x

= 10 × 8 + 2

= 80 + 2

= 82
