Question 59
The average of $$T_{1}$$ and $$T_{2}$$ is 15. The average of $$T_{3}$$ and $$T_{4}$$ is 35. What is the average of $$T_{1}, T_{2}, T_{3}$$ and $$T_{4}$$?
Solution
The average of $$T_{1}$$ and $$T_{2}$$ is 15.
Sum of $$T_{1}$$ and $$T_{2}$$ = $$15\times2$$ = 30
The average of $$T_{3}$$ and $$T_{4}$$ is 35.
Sum of $$T_{3}$$ and $$T_{4}$$ = $$35\times2$$ = 70
Average of $$T_{1}, T_{2}, T_{3}$$ and $$T_{4}$$ = $$\frac{sum\ of\ data}{number\ of\ data}$$
= $$\frac{30+70}{4}$$
= $$\frac{100}{4}$$
= 25
