At a school carnival, each woman received 5 packets of lollipops and each man received 6 packets of lollipops. Each accompanying child received 7 packets of lollipops.
37 of the people at the school carnival were child. The ratio of the number of women to the number of men at the carnival was 3 : 8. Given that only 2898 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 11 and 4 is 44.
Number of packets of lollipops given away
= 12 u x 5 + 32 u x 6 + 33 u x 7
= 60 u + 192 u + 231 u
= 483 u
483 u = 2898
1 u = 2898 ÷ 483 = 6
Number of people at the carnival
= 44 u + 33 u
= 77 u
= 77 x 6
= 462
Answer(s): 462
