Answer:
The correct answer is "
".
Step-by-step explanation:
The figure according to the given question is attached below.
Given that,
Number of people,
p = 4
Let the suitable notations are:
a, b, c, x, y, z and p
where,
Only leader M = x
Only champion M = y
Only range M = z
Exactly two medals = a+b+c
All three medals = p
The equations will be:
...(1)
...(2)
...(3)
...(4)
Now,
From equation (1), (2) and (3), we get


...(5)
By applying subtraction between equation (5) and (4), we get



11
n-30=14-3n
you add 3n to both sides
then you'll have 4n-30=14
you add 30 to 14
4n=44
n=11
