There are four times as many purple skirts as brown skirts in a sale. If there are 190 purple and brown skirts altogether,
- how many purple skirts are there?
- how many more purple skirts than brown skirts?
(a)
Number of brown skirts = 1 u
Number of purple skirts
= 4 x 1 u
= 4 u
Total number of skirts
= 4 u + 1 u
= 5 u
5 u = 190
1 u = 190 ÷ 5 = 38
Number of purple skirts
= 4 u
= 4 x 38
= 152
(b)
Number of more purple skirts than brown skirts
= 4 u - 1 u
= 3 u
= 3 x 38
= 114
Answer(s): (a) 152; (b) 114
