A's salary is 15% less than B's salary. B's salary is 30% less than C's salary. By how much percent approximately, is C's salary more than A's salary?
Answer & explanation
Correct answer: option 1
15% = \(\frac{3}{20}\)
Ratio of A to B's salary = 17 : 20
30% = \(\frac{3}{10}\)
Ratio of B's salary to C's = 7 : 10
Overall ratio of salary of A , B & C
= 119 : 140 : 200
Difference in salary of A & C = 200 - 119 = 81
Required percentage = \(\frac{81}{119}\) × 100 = 68.06%
= 68% ( approx)
