Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 240
Four numbers are in the ratio of 2 : 5 : 3 : 8.
Let four numbers be 2x,5x,3x,8x.
A/c to question,
2x + 3x + 5x + 8x = 432.
18x = 432 , x = 24.
First number = 24 × 2 = 48.
Fourth number = 24 × 8 = 192.
Sum = 48 + 192 = 240.
