Question
Select the correct answerFive farmers have 7,9,11,13 & 14 apple trees respectively in their orchards. Last year each of them discovered that every tree in their own orchard yields exactly the same number of apples. Further, if the 3rd farmer gives one apple to the 1st and the 5th gives 3 to each of the 2nd & d 4th, they would all exactly have the same number of apples, what were the yields per tree in the orchards of the 3rd & 4th farmers ?Options17 & 9 9 & 9 11 & 9 9 & 11
Solution
The question is asking for the yield per tree in the orchards of the 3rd and 4th farmers.
Let's denote the yield per tree for each farmer as a, b, c, d, and e for the 1st, 2nd, 3rd, 4th, and 5th farmer respectively.
From the problem, we know that:
7a + 9b + 11c + 13d + 14e = 5x (where x is the total number of apples each farmer would have after the redistribution)
After the redistribution, the 3rd farmer gives one apple to the 1st farmer and the 5th farmer gives 3 apples to each of the 2nd and 4th farmers. So, the equation becomes:
(7a+1) + (9b+3) + (11c-1) + (13d+3) + (14e-6) = 5x
Solving these two equations, we can find the values of a, b, c, d, and e.
However, since we are only interested in the yields of the 3rd and 4th farmers, we are looking for the values of c and d.
By comparing the options given, we can see that the only possible solution that fits the conditions of the problem is 9 & 11.
Therefore, the yields per tree in the orchards of the 3rd and 4th farmers were 9 and 11 respectively.
