Question

30% passengers from a train got down at station A. 50% of the remaining passengers
get down at station B. If there were still 350 passengers in the train, how many passengers
were there in the train before station A? ​

Answer 1

Step-by-step explanation:

Let the total passengers be x

Passengers got down at station A=3÷10 x

Passengers got down at station B=1÷2x

Passengers in the train = 350

A/Q

3/10 x+1/2x + 350 = x

8x/10+350=x

x-8x/10=350

2x/10=350

2x=3500

x=1750

The total passengers were 1750

Answer 2

Answer:

5000

Step-by-step explanation:

Let the mo. of passengers on the bus be x

Given

30% of then got down ar station A

i.e

100/30x

people got down at station A and Remaining people on the bus

100/70x

also given that

70% of remaining people got down at station B

i.e,

100/70 ( 100/70x)= 100/49 x

i.e,

100/49x

people got down ae station B

Remaining people on the bus x−

100/30x −

100/49x = 100/21x

Given

Remaining people were =1050

100/21x = 1050

x=5000

∴ there are 5000 people on the bus.
