Question

One apple weighs 75 grams and one orange weighs 40 grams. Determine the weight of x apples and y oranges.

Answer 1

Hint: Use unitary method to find the weights of the x apples and y oranges. So if one apple is ‘a’ grams, then ‘x’ apples will be of weight ‘ax’ grams. Similarly, apply the same concept for y oranges.

Complete step-by-step answer:
In the question, we have to find the weight of x apples and y oranges, when it is given that one apple weighs 75 grams and one orange weighs 40 grams.
So, here if the weight of one piece of apple is known, then applying the unitary method, it will be easy to find the weight of any number of apples. Similarly, if the weight of one piece of orange is known, then applying the unitary method, it will be easy to find the weight of any number of oranges. Now, apply the unitary method that if one item is ‘a’ grams, then ‘x’ number of the same items will be of weight ‘ax’ grams.
So, here it is given that one apple weighs 75 grams, which means that the weight of x apples will be (75x) grams.
Similarly, here it is also given that one orange weighs 40 grams, which means that the weight of y oranges will be (40y) grams.
Hence, the weight of x apples is (75x) grams and weight of y oranges is (40y) grams.

Note: When we are applying the unitary method, then make sure it is applied carefully, where we first find the value of 1 unit and then the value of the required number of units of the same item.
