In November's Math Meet, the Little Monsters of Beast Academy solved 1/3 of the problems. In March's Math Meet, they solved 2/7 of the problems. (There might be different numbers of problems asked in November and March.)
In total, the Little Monsters solved 15 of 28 problems over both Math Meets. How many problems were asked at March's Math Meet?
Let the number of problems in November ==N
Let the number of problems in March ==M
1/3N + 2/7M ==15........................(1)
N + M == 28.................................(2), solve for N, M
N==147 and M== - 119 !!!!!! Do these numbers make sense to you ??
I think there is a major mistake in your question. Check it carefully.
