GATE CS 2023 Q4 — General Aptitude

Let the total number of pregnant women be $T$.

From the given data:

• The number of pregnant women who received medical care at least once is $90\%$ of $T$, which is $0.90 T$.
• Of these women, $60\%$ received medical care from doctors.

Therefore, the number of pregnant women who received medical care at least once from a doctor is:

This represents $54\%$ of the total pregnant women ($T$). Since $54\% > 50\%$, we can conclude with certainty that more than half of the pregnant women received medical care at least once from a doctor.

Thus, Option A is the correct statement.
