Hello,
Greetings for the day!
This DS question is an easy question based on doing basic percentage calculations. Therefore, this is a sort of question that you can probably expect in the initial quarter of the Quant section on an actual test.
In the question, we are required to find out, what percentage the coats made by the seamstress represents, in comparison to the total output of coats of the shop.
This can be found out using the expression,
(Number of coats made by the seamstress / Total coat outputs of the shop) x 100
We already have the data about the numerator since the question says that the seamstress made 65 coats. Hence, we need data about the denominator from the statements.
Using Statement I alone, we know that the total coat output of the shop is 325. Hence, we can determine a unique value for the percentage, by plugging in the values known in the expression above. Therefore, statement I alone is sufficient to answer the question asked.
Using statement II alone, we know for sure that the seamstress had made 20% of the total output of the shop’s coats since 1/5 represents 20%. Therefore, statement II alone is sufficient to answer the question asked.
We can conclude that the correct answer option is D since each statement alone is sufficient to answer the question.
Hope this helps!
