The total number of contestants who received Merit certificates and Participation certificates is the combined repeated identity. LCM of 5 and 2 is 10.
Total points awarded
= 105 u + 30 u + 12 u
= 147 u
147 u = 735
1 u = 735 ÷ 147 = 5
Number of contestants in the quiz
= 15 u + 6 u + 4 u
= 25 u
= 25 x 5
= 125
Answer(s): 125
