Suppose the heaviest of apples is 160 grams for easier understanding

Since 45% -> 81g-160g
so 55% -> 0g-81g
since 81% -> 0g-145g
so 81g-145 = 81-55=26%

Let's say there are 100 apples in the barrel.

45% of the apples weigh MORE THAN 81 grams
This means 55% of the apples weigh LESS THAN OR EQUAL to 81 grams
In other words, 55 apples weigh LESS THAN OR EQUAL to 81 grams

81% of the apples weigh LESS THAN 145 grams
This means 19% of the apples weigh MORE THAN OR EQUAL to 145 grams
In other words, 19 apples weigh MORE THAN OR EQUAL to 145 grams

To summarize, we have:
....55 apples....81 grams.............145 grams... 19 apples...

55 + 19 = 74
We've now accounted for 74 apples, which means the remaining 26 apples must be BETWEEN 81 grams and 145 grams.

Answer: C

Cheers,
Brent

\(? = x\)

\(100 = 45 + 81 - x\,\,\,\,\left[ {{\rm{simplifier}}} \right]\,\,\,\,\,\,\,\, \Rightarrow \,\,\,\,\,\,\,? = x = 26\)


We follow the notations and rationale taught in the GMATH method.

Fabio.

Since 45% of the apples weigh more than 81 grams, and 81% of the apples weigh less than 145 grams, 45 + 81 - 100 = 26 percent weigh between 81 and 145 grams.

Let's assume that the barrel contains 100 apples.

45% weigh more than 81 gms. Thus, 45 apples we keep; 55 we discard.

Now, 81% weigh less than 145 gms. Thus, out of 45 apples from earlier, 19 apples will have to be removed from consideration.

Thus, 45 - 19 = 26.

Ans. C.
