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%
