Answer : Option C
Explanation :
Let A = 2k, B = 3k and C = 5k.
A's new salary =\(\frac { 11 5} { 100 }\) of 2k = [\(\frac { 11 5} { 100 }\) x 2k] = \( \frac { 23k } { 10 } \)
B's new salary =\(\frac { 11 0} { 100 }\)of 3k = [\(\frac { 11 0} { 100 }\) x 3k ] = \( \frac { 33k } { 10 } \)
C's new salary = \(\frac { 12 0} { 100 }\) of 5k =[ \(\frac { 12 0} { 100 }\)x 5k] = 6k
New ratio[\( \frac { 23k } { 10 } \):\( \frac { 33k } { 10 } \):6k] = 23:33;60
