SSC CHSL 20213)Three numbers are in the ratio \(\frac{1}{4} : \frac{5}{9} : \frac{7}{12}\). The difference between the greatest and the smallest number is 180. Find the sum of all the three numbers.
750
\(\frac{1}{4} : \frac{5}{9} : \frac{7}{12} =>9:20:21\)
hence, 21x - 9x = 180, x = 15
sum of numbers = 9x + 20x + 21x = 50x = 750
