Answer 1

Heya !!




Let three numbers are 4X , 5X and 7X.



Let smallest number be 4x and largest number be 7x.

According to the question,




7x + 4x = 5x + 72





11x - 5x = 72




6x = 72


x = 72/6



X = 12




Largest number = 7x = 7 × 12 = 84



Smallest number = 4x = 4 × 12 = 48


And,



Third number = 5x = 5 × 12 = 60.
