A. 60
B. 144
C. 120
D. None of these
🧠 Explanation:
If three-fourths of a number is 60 more than one-third of it, the number is 144. Let the number be x; then (3/4)x = (1/3)x + 60. Solving, (3/4)x − (1/3)x = 60, or (9/12)x − (4/12)x = 60, so (5/12)x = 60, giving x = 60 × 12/5 = 144. This algebraic problem tests fraction manipulation, key in mathematics. Such equations are used in finance or engineering, emphasizing the importance of solving for unknowns in practical scenarios.
