Okay so as per question we know that the 4 coins could be of value 0.01, 0.05, 0.10 or 0.25, they could be of any value,
Now, when we see the first option it does tell us about one coin being 0.01 but it doesn’t give us any information about the other 3 coins hence insufficient
Cross out A and D
Coming to the second statement it tells us that the change could have also consisted of just 2 coins with a value of 0.01, 0.05, 0.10 or 0.25, but again we don’t know what is the exact value of those coins so again insufficient cross out B
Statements combined
We know that 1 coin is 0.01
The change could’ve also consisted of only 2 coins with a value of 0.01,0.05,0.1,0.25
Notice that we can’t go anywhere from here as we still do not have a clear picture about the other 3 coins other than the one with 0.01 hence cross out C
ANSWER IS E
