let three numbers be X Y Z

sum of three numbers as per question X+Y+Z = 280

**X Y Z**

2 : 3 : 3

4 : 4 : 5

8 : 12 : 15

**NOTE WHEN ONLY TWO VALUE ARE GIVEN REPEAT THE VALUE AGAIN AS DONE ABOVE**

sum of three numbers as per question 8+12+15 = 35

MEANS 35 represents 280

1 represents 280/35= 8

in question they asked to find the second number with is 12, so 12×8 =96

`ANSWER 96`
