At a school carnival, each man received 4 packets of lollipops and each woman received 5 packets of lollipops. Each accompanying child received 6 packets of lollipops.
37 of the people at the school carnival were child. The ratio of the number of men to the number of women at the carnival was 4 : 5. Given that only 2934 packets of lollipops were given away, how many people were there at the carnival?

47 The number of adults is the combined repeated identity. Make the number of adults the same. LCM of 9 and 4 is 36.
Number of packets of lollipops given away
= 16 u x 4 + 20 u x 5 + 27 u x 6
= 64 u + 100 u + 162 u
= 326 u
326 u = 2934
1 u = 2934 ÷ 326 = 9
Number of people at the carnival
= 36 u + 27 u
= 63 u
= 63 x 9
= 567
Answer(s): 567
