Question

In a follow up survey of the same kids two years later, it was found that all the kids were now in school. Of the kids who were not in school earlier, in one region, $25\%$ were in G now, whereas the rest were enrolled in 12; in the second region, all such kids were in G now; while in the third region, $50\%$ of such kids had now joined G while the rest had joined P. As a result, in all three regions put together, $50\%$ of the kids who were earlier out of school had joined G. It was also seen that no surveyed kid had changed schools.
What percentage of the surveyed kids in S, whose mothers had dropped out before completing primary education, were in G now?

• A. $94.7\%$
• B. $89.5\%$
• C. $93.4\%$
• D. Cannot be determined from the given information

Answer 1

The correct option is A

$94.7\%$

From previous question, we have
Number of kids from S, who had not gone to school earlier and whose mothers had dropped out of primary education, joining government school (G) now = 300
From the table, number of kids from S already in government school (G) whose mothers had not completed primary education = 5100
Total number of kids from S in government school (G) whose mothers had not completed primary education = 5400
Required percentage $=\left(\frac{5400}{5700}\right)\times 100=94.74\%$
