Question

1 by 8 of the passengers of the train for children if there were 40 children travelling in the train on the certain day how many adults were there in the train that day

Answer 1

Let the total number of passengers be a

According to question,

1/8 of a = 40

=> a/8 = 40

=> a = 320

Total number of passengers = 320

Number of adults = 320 - 40 = 280

Answer 2

Given, 1/8 of the passengers were children and number of children was 40

Let total number of passengers be x,

1/8 of x = number on children

x/8 = 40

x = 40 * 8

x = 320

Hence, number of passengers was 320.

Number of adults = 320 - 40 

                               =  280
