Question

In a train accident, 10% of the passenger died on the spot and 5%of the rest, later in the hospital.If the number of survivors is 1710, how many passengers were originally there​

Answer 1

Step-by-step explanation:

In the accident, 10% died on the spot. So 90% survived on the spot. Out of this, 5% died later in hospital. That means, a total of (10 + 90*0.05), or 14.5% of original number of passengers died. Survivors are therefore 85.5%, which is 1710. Hence original number of passengers is (1710/0.855), which is 2000
