We have a question: Ryan's party was 4 times as huge as Taylor's birthday party. If both parties combined had 240 people, how many people were there at Ryan's party?
And an answer: 192
So how you got the answer?
To get the number of people at Taylor's party, we'll assume there were n people at his party. The total number of people at Ryan's party is 4 * n, four times the number of attendees at Taylor's party. Combined, there were 4n + n = 240 people at both parties. This translates to 5n = 240. The total number of people at Taylor's party is n = 240 / 5. There were n = 48 people at Taylor's party. Since Ryan's party was 4 times as huge as Taylor's party, at Ryan's party, there were 48 * 4 = 192 people.

We have a question: At a shop in Japan, women's T-shirts are sold every 30 minutes for $18, and men's T-shirts are sold every 40 minutes for $15. This shop is open from 10 am until 10 pm. How much does the shop earn selling T-shirts per week?
And an answer: 4914
So how you got the answer?
First, the shop is open 12 hours * 60 minutes = 720 minutes per day. So, 720 / 30 = 24 women's T - shirts sold per day. The shop earns 24 * $18 = $432 selling women's T - shirts per day. Similarly, 720 / 40 = 18 men's T - shirts are sold per day. The shop earns 18 * $15 = $270 selling men's T - shirts per day. The shop earns $432 + $270 = $702 per day selling T - shirts. The shop earns $702 * 7 = $4914 per week.
