Let A = 2k, B = 3k and C = 5k.
A's new salary = \(\frac{115}{100} of 2k = \left(\frac{115}{100}\times2k\right) = \frac{23k}{10}\)
B's new salary = \(\frac{110}{100} of 3k = \left(\frac{110}{100}\times3k\right) = \frac{33k}{10}\)
C's new salary = \(\frac{120}{100} of 5k = \left(\frac{120}{100}\times5k\right) = 6k
\)
Therefore New ratio \(\left(\frac{23k}{10}:\frac{33k}{10}:6k\right) = 23:33:60\)
