25 persons will get both bottle and t – shirt.
<u>Solution:</u>
Given, every 8th person that goes into a store gets a free bottle.
And every 10th person that goes into a store gets a t-shirt.
There are 100 bottles and 100 t shirts to give out.
We have to find how many people get a t shirt and a bottle
Now, as there are 100 t- shirts, last person to get t – shirt is:
10 x 100 = 1000th person will get last t – shirt
We have to find lcm of 8 and 10, to know who gets both bottle and t – shirt.
So, L.C.M of 8 and 10 = lcm(8, 10)
= 2 x lcm(4, 5)
= 2 x 4 x 5 [ as no common factors available for 4 and 5 ]
= 40
So, every 40th person will get both bottle and t – shirt.
Then, out of 1000 people, number of people who get both bottle and t – shirt =
