What was the amount of money awarded to the recipient of a

OA has to be E. I am increasingly seeing such CR based assumption trap Quant question. Interesting shift. I also saw a similar style question on speed time and distance.

50 % was given immediately doesn't mean that the other 50% would be given after completion of research. Big assumption here.

Statement 1 gives us only the percent of amount but not the quantity or amount itself so clearly insufficient
Statement 2 tells us that $75,000 was to be given to the recipient upon completion of research. This doesn't tell us anything more because we don't know how much percent of total does the $ 75000 represent so insufficient

Combining both statements we would be tempted to think that if 50 % is paid immediately and $75000 is paid at the end then $75000 would represent the remaining 50 % . But it is not such a case we don't know if researcher was paid any money in between the research and whether $ 75000 is 50 % of total amount or even less than that So insufficient

Correct Answer - E

Option 1. Is clearly not sufficient on its own.
Option 2. Is a trap because it is nowhere mentioned that the 75,000$ is the remaining 50%.

So Answer is E
