Explanation:

Mike testing 1234 1234

Answer 2

Answer:

126

246

Explanation:

p1=30#who solved 1 and 2

p2=26#who solved 2 and 3

p3=28#who solved 1 and 3

q=14#who solved 1,2 and 3

total=345#total number of employees

r=43#did'nt participated at all

m=total-r

s1=p1-q#only shared between p1 and p2

s2=p2-q#only shared between p2 and p3

s3=p3-q#only shared between p3 and p1  

x=(m-(s1+s2+s3+q))//3

print(x)

ans1=x+s1+q+s3

ans2=3*x

print(ans1)

print(ans2)
