options B............

Answer 2

Answer:

(315,9)

Let the two numbers be 'x' and 'y' respectively.then,

x+y=324

9 is their HCF

so each no. must be divisible by 9, where x and y are coprime.

so let x=9a and y= 9b ;

now, 9a + 9b=216

a + b =324/9

a + b=36

There are two pairs (x, y) which satisfy the condition, (13,23) and (5,31). The possible answers are (117, 207) and (45, 279).
