40% passengers from a tarin got down at station a 60% of the remainimg passengers got down at statiok b if there were still 540 passengers in the train how many passengers were
Answers
Answer:
There were originally 2250 passengers in the train
Step-by-step explanation:
Let "x" be the original number of passengers
We are given that 40% of them got down at Station A.
This means that 60% of them were still in the train
=> No. of passengers in train after Station A = 60% of x
=> No. of passengers in train after Station A = 0.6*x
Now, we are also given that 60% of those that remained got down at Station B.
Clearly, this is equal to:
60% of (0.6*x)
= 0.6 * (0.6*x)
= 0.36*x
Hence, 0.36*x got down at Station B.
Hence, the number of passengers that remained after Station B
= 0.6*x - 0.36*x
= 0.24*x
This number is given as 5400
∴ 0.24*x = 5400
∴ x = 5400/0.24
∴ x = 2250
Original number of passengers in the train = 2250
Verification:
Original passengers = 2250
No. of passengers getting down at Station A = 40% of 2250 = 900
No. of passengers remaining in train after Station A = 2250-900 = 1350
No. of passengers getting down at Station B = 60% of 1350 = 810
No. of passengers remaining in train after Station B = 1350 - 810 = 540
Thus verified
