Delhi Police Constable Exam Model Paper 5

Case I:
As, numerator is same and denumerator of 4/9 is greater than 4/7,
Hence, (4/9) < (4/7)
∴ Statement I is false.
Case II:
$\frac{5}{7}=\left(\frac{5}{7}\right)\times \left(\frac{9}{9}\right)=\frac{45}{63}$
$\frac{4}{9}=\left(\frac{4}{9}\right)\times \left(\frac{7}{7}\right)=\frac{28}{63}$
As, denumerator is same and numerator of 45/63 is greater than 28/63
Hence, $\frac{45}{63}>\frac{28}{63}\mathit{i}.\mathit{e}.\frac{5}{7}>\frac{4}{9}$
∴ Statement II true.
Hence, only Statement II is true.
