Z1 |
690 |
|
Z2 |
710 |
|
Z3 |
830 |
|
Z4 |
670 |
|
Z5 |
900 |
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.]
Answer & explanation
Correct answer: option 3
Total number of trains that originate in Z3 and Z4 = 830 + 670 = 1500
Total number of trains originate in all the 5 zone together = 690 +710 + 830 + 670 + 900
= 3800
Required percentage = \(\frac{1500 }{3800}\) × 100
= 39.47%
