Question 63
The following table shows the number of trains that originate in the five different zones of the railway network of a country.
The total number of trains that originate in Z3 and Z4 taken together is what percentage of the total number of trains that originate in all the 5 zones taken together? [Give your answer correct to 2 decimal places.]
Solution
The total number of trains that originate in Z3 and Z4 taken together = 830+670
= 1500
total number of trains that originate in all the 5 zones taken together = 690+710+830+670+900
= 3800
Percentage = $$\frac{1500}{3800}\times100$$
= $$\frac{750}{19}$$
= 39.47%
