Question
Select the correct answerA, B and C together earn Rs. 300 per day, while A and C together earn Rs. 188 and B and C together earn Rs. 152. The daily earning of C isOptionsRs. 68Rs.40Rs. 112Rs. 150
Solution
To solve this problem, we can use the method of elimination.
-
First, add the total earnings of A, B, and C (Rs. 300) to the earnings of A and C (Rs. 188) and B and C (Rs. 152). This gives us Rs. 640.
-
However, in this sum, we have counted the earnings of A, B, and C twice. So, we divide Rs. 640 by 2 to get the correct total earnings of A, B, and C. This gives us Rs. 320.
-
Now, subtract the total earnings of A, B, and C (Rs. 300) from Rs. 320. This gives us the daily earnings of C, which is Rs. 20.
However, Rs. 20 is not an option in the given choices. It seems there might be a mistake in the problem or the options provided.
