Answer:
C. 10 000
Step-by-step explanation:
If we called:
x = children who have been vacinated against rubella only
2x = children who have been vaccinated against mumps
y = children who have been vaccinated agains both
Children who have been vaccinated against mumps only = x - y
And we know that y = 2*(x-y)
=> 2y = 3x
y = 5000
There fore x = 7500
The number of children who have been vaccinated against rubella
= 2x - y = 2*7500 - 5000 = 15 000 - 5000 = 10 000
Answer:
Option C -> None of the above.
Step-by-step explanation:
Given-
2 r + ( t + r )

<em>⇒ 3 r + t</em>
∵ 2 r + ( t + r ) = 3 r + t.
∴ The given expression is equivalent to Option C : None of the above.
