A. 30
B. 55
C. 27 
D. 45

🧠 Explanation:

For a qualification with 120 total marks, 2/5 (48 marks) were for coursework, leaving 72 marks for the written paper. Of the written paper, 3/8 were for the mental test, so 3/8 of 72 = 27 marks. This calculation involves basic fractions and proportions, key in academic assessments. Understanding such problems aids in mastering mathematical reasoning, applicable in education, finance, or data analysis. The mental test’s share highlights the importance of structured evaluation in testing diverse skills, ensuring clarity in how marks are distributed in academic systems.
