Let amount deposited by Olivia into Bank A be P. Rate of interest be ra.
Let the amount deposited by Ethan into Bank B be D. Rate of interest be rb.
We need to find:
Is P > D ? Statement 1: (1) After one year, the amount of interest Olivia earned on her deposit was 20% greater than the amount of interest Ethan earned on his deposit.Interest earned by Olivia = (120/100)* Interest earned by Ethan.
P* ra = (120/100)* D *rb
since, we don’t know P,D, ra or rb.
insufficient Statement 2: (2) Bank A offers a simple annual interest rate of 5%, and Bank B offers a simple annual interest rate of 4%.
P*5% compared with D*4%. Since, we don’t know P and D.
Insufficient Combining both Statements 1 and 2, we get
P* 5% = (120/100)* D *4%
P/D = 24/25
The amount invested by Olivia is less than the Amount invested by Ethan.
P: D = 24:25.
Hence,
Sufficient Option C
