The number of people who travelled by Delhi metro on Monday was $56,940$; on Tuesday was $48,856$ and on Wednesday was \[86,756\]. How many people in all travelled by Delhi metro on these three days?
Hint: First we have to define what the terms we need to solve the problem are. Since they were asking us to find the total number of people who travelled by the Delhi metro train, we need to know about the additional property (sum of the numbers) given as the answer for the given question. Also, the travel will happen only on Monday, Tuesday, and Wednesday so we need to find the total, which means we need to add these three days of travel to get the answer.
Complete step-by-step solution: Since the total number of people who travel in the metro on the Monday to the city Delhi is $ \Rightarrow 56,940$ (fifty-six thousand nine hundred and forty people who travelled in metro of the city Delhi) Also, the number of people who travelled by Delhi on the metro on the day Tuesday is $ \Rightarrow 48,856$ If they asking to find the total number of people who travel in the two days, means we need to add or sum the Monday and the Tuesdays only; they asking all three which means we need another result that is The number of people who travelled as like as Wednesday is \[ \Rightarrow 86,756\] so we have all the three days travelled details hence by the property of addition we will act now the answer; Hence the total number, means we need to add all the three days people travelled by Delhi metro in these all three days is $ \Rightarrow 56940 + 48856 + 86756$ (the three days with people travels detains sum) Therefore, acting the addition property, we get $56940 + 48856 + 86756 \Rightarrow 1,92,552$ is the number of people who travel on the three days
Note: since they are asking us to find the total so only, we using the addition property to sum of the traveled people if the question about the average means we need to mean formula to find the average; hence there are nearly two lakhs people who travelled only the three days.
