Runs scored by Sachin in a charity match are 10 more than the balls faced by Lara. The number of balls faced by Sachin is 5 less than the runs scored by Lara. Together, they have scored 105 runs and Sachin faced 10 balls less than the balls faced by Lara. How many runs were scored by Sachin?
Explanation
To solve this problem, we will use a system of linear equations. Let us define our variables first:
RS = Runs scored by Sachin
RL = Runs scored by Lara
BS = Balls faced by Sachin
BL = Balls faced by Lara
Step 1: Translate the statements into equations
Based on the text in image_8270dc.png, we can derive the following equations:
RS=BL+10
BS=RL−5
RS+RL=105
BS=BL−10
Step 2: Solve the system of equations
From equation (4), we can express BL in terms of BS:
BL=BS+10
Now, substitute this into equation (1) to find RS:
RS=(BS+10)+10
RS=BS+20
From equation (2), we can express RL in terms of BS:
RL=BS+5
Now, substitute the expressions for RS and RL into equation (3):
(BS+20)+(BS+5)=105
2BS+25=105
2BS=80
BS=40
Step 3: Calculate the final answer
Now that we have BS=40, we can substitute this back into our expression for RS:
RS=BS+20
RS=40+20
RS=60
Conclusion:
The total runs scored by Sachin is 60. Therefore, the correct option is 3.
