At the laser tag park, there were 40% as many women as men and 20% more children than women. Given that there were 8 more children than women at the laser tag park, how many adults were there altogether?

10 u |
25 u |
12 u |
40% =
40100 =
25Women : Men = 2 : 5
100% + 20% = 120%
120% =
120100 =
65 Women : Children = 5 : 6
The number of women is repeated. Make the number of women the same. LCM of 2 and 5 is 10.
Number of more children than women
= 12 u - 10 u
= 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Number of adults
= 10 u + 25 u
= 35 u
= 35 x 4
= 140
Answer(s): 140
