Equal amounts of water were poured into two empty jars of different capacities, which made one jar 1/4 full and the other jar 1/3 full. If the water in the jar with lesser capacity is then poured into the jar with the greater capacity, what fraction of the larger jar will be filled with water?
A. 1/7
B. 2/7
C. 1/2
D. 7/12
E. 2/3
Answer: C
Answer: C
The jar that is 1/3 full is smaller
water in jar 1 = water in jar 2
jar 1 is now twice as full (1/4)*2 = 1/2
water in jar 1 = water in jar 2
jar 1 is now twice as full (1/4)*2 = 1/2
or
1/4 + 1/4 = 1/2
