The salaries A, B, C are in the ratio 2 : 3 : 5. If the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be new ratio of their salaries?
3 : 3 : 10
10 : 11 : 20
23 : 33 : 60
Cannot be determined
Explanation:
Let A = 2k, B = 3k and C = 5k
A's new salary = $\dfrac{115}{100} of 2 k = (\dfrac{115}{100}\times 2 k ) = \dfrac{23 k}{10}$
B's new salary = $\dfrac{110}{100} of 3 k = (\dfrac{110}{100}\times 3 k ) = \dfrac{33 k}{10}$
C's new salary = $\dfrac{120}{100} of 5 k = (\dfrac{120}{100}\times 5 k ) = 6 k$
ஃ New ratio ($\dfrac{23k}{10} : \dfrac{33k}{10}: 6 k) $= 23 : 33 : 60
