Millie, Monica, and Marius are taking subjects for school. Millie takes three more subjects than Marius, who takes 4 subjects more than Monica. If Monica took 10 subjects, how many subjects all take altogether? Let's be accurate as possible.
If Monica took ten subjects, Marius took 10 + 4 = 14 subjects. Marius and Monica have 14 + 10 = 24 subjects which they've taken. Since Millie is taking three more subjects than Marius, she is taking 14 + 3 = 17 subjects. Together, the three have taken 24 + 17 = 41 subjects.
The answer: 41.
