Answer 2

Given:

a set S of integers from 1 to 250. A denotes the set of integers divisible by 3,8 denotes the set of integers divisible by 5 and C denotes the set of integers divisible by 7

To Find:

Number of elements in A∩B

Step-by-step explanation:

• A set denotes the elements which are divisible by $3$
• B set denotes the elements which are divisible by $5$.
• elements common to both A and  B will be divided by $3\times 5=15$
• As the elements are from $1 \ to\ 250$ so $=250\div 15=16.66$
• So there are 16 integers in S which are common to both A and B set

The final answer is 16
