Answer: (2) 192

Explanation:-
The ratio of first and second numbers = 2: 3
The ratio of second and third numbers = 5: 8

Then, the ratio of first, second and third numbers = 2 x 5: 3 x 5: 3 x 8
= 10: 15: 24

The sum of the three numbers = 392
Then, 10X + 15X + 24X = 392
59 X = 392
X = 392/59
X = 8

Then, the value of third number is 24X = 24 x 8 = 192

Hence, the answer is (2) 192.
