Answer:
9 and 24
Explanation:
Recall that for a given number A and the given ratio x : y, the two parts having the ratio x : y is (xA) / (x + y) and (yA) / (x + y).
Given A = 33, x = 3, y = 8,
- (xA) / (x + y) = (3*33) / (11)
 -  = 99/11
 -  = 9
 
And,
- (yA) / (x + y) = (8*33) / (11)
 -  = 264/11
 -  = 24
 
Hence, the parts are 9 and 24 respectively.
