Q1. If 1/4 writing, 1/6 reading, and 1/8 designing are participated in different contests and 33 participants of mathematics, then the total number of participants are:
Answer: 72
Explanation: Fractions for writing (1/4), reading (1/6), and designing (1/8) sum to 13/24, leaving 11/24 for mathematics; 11/24 × total = 33, so total = 72.
