At the night market, there were 75% as many men as women and 20% more children than men. Given that there were 15 less men than children at the night market, how many adults were there altogether?
| Men |
Women |
Children |
| 3x5 |
4x5 |
|
| 5x3 |
|
6x3 |
| 15 u |
20 u |
18 u |
75% =
75100 =
34Men : Women = 3 : 4
100% + 20% = 120%
120% =
120100 =
65 Men : Children = 5 : 6
The number of men is repeated. Make the number of men the same. LCM of 3 and 5 is 15.
Number of less men than children
= 18 u - 15 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of adults
= 15 u + 20 u
= 35 u
= 35 x 5
= 175
Answer(s): 175
