Question
Jack bought 10 apples, 15 pears and Jill bought 20 apples and some pears. Jack paid Rs. 20 for his purchase and Jill paid Rs. 40 for his purchase. How many pears did Jill buy?Choices:- 45 30 15 Cannot be determined
Solution
The problem can be solved using the method of simultaneous equations.
Let's denote the cost of an apple as 'a' and the cost of a pear as 'p'.
From the problem, we know that:
-
Jack bought 10 apples and 15 pears for Rs. 20. So, 10a + 15p = 20.
-
Jill bought 20 apples and some pears for Rs. 40. So, 20a + xp = 40, where x is the number of pears Jill bought.
We can simplify the first equation to a + 1.5p = 2.
Substituting the value of 'a' from the first equation into the second equation, we get 2 + 1.5x = 40.
Solving for x, we get x = 25.33.
Since the number of pears must be a whole number, it is not possible to determine the exact number of pears Jill bought based on the information given.
So, the answer is "Cannot be determined".
