The total number of pupils who received Merit certificates and Participation certificates is the combined repeated identity. LCM of 9 and 2 is 18.
Total points awarded
= 72 u + 40 u + 10 u
= 122 u
122 u = 1098
1 u = 1098 ÷ 122 = 9
Number of pupils who received Participation certificates
= 10 u
= 10 x 9
= 90
Answer(s): 90
