Question: In a cricket match, first three batsmen scored 115 runs in total. If the first batsman scored 23 runs, second batsman scored 51 runs then how many runs third batsman scored ?
Answer: This example is also simple addition/subtraction example. The total score of first three batsmen are 115, lets write this in left hand side of our equation as below:
115 = score by 1^{st} player + Score by 2^{nd} Player + Score by 3^{rd} Player
Now write scores of 1^{st} and 2^{nd} players at their respective place, so the equation will look like following:
115 = 23 + 51 + Score by 3^{rd} Player 115 = 74 + Score by 3^{rd} player Hence; Score by 3^{rd} Player = 115 − 74, which comes as: 41
So, score by 3^{rd} player is 41 runs.
