The bag will often contain all three items every 70 bags ⇒ answer C
Step-by-step explanation:
At a display booth at an amusement park, every visitor gets a gift bag
according to these information:
1. Hat Every 2nd visitor
2. T-shirt Every 7th visitor
3. Backpack Every 10th visitor
We need to know how often a bag will contain all three items
To solve this problem you must find a number divisible by 2, 7, and 10
To find that number start with the multiples of the largest one and
check them with the other two numbers
∵ The largest number is 10
∵ The multiples of 10 are 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , .......
- Look for the first multiple of 10 is divisible by 7
∵ 70 is the first multiple of 10 divisible by 7
∵ 70 is divisible by 2 because its even number
∴ 70 is the smallest number divisible by 2, 7 and 10
The bag will often contain all three items every 70 bags
