A earns 20% more than B but 25% less than C. If B earns Rs. 900 less than C, find the earnings of C :
Explanation:
Let the earnings of C be 'c'.
⇒ Earnings of A = 25% less than earnings of C = 3/4 × c
⇒ Earnings of A = 20% more than earnings of B ⇒ 3/4 × c = 6/5 × earnings of B ⇒ Earnings of B = 5/8 × c
Givne, c - 5/8 × c = 900 ⇒ 3/8 × c = 900 ⇒ c = 2400
Hence, option (d).
