Correct Answer: 64 : 81

Solution : $1\frac{1}{2} : 1\frac{1}{3}$
$=\frac{3}{2}$ : $\frac{4}{3}$
After squaring the fractions, we get,
⇒ $\frac{9}{4}:\frac{16}{9}$
Their reciprocals are,
⇒ $\frac{4}{9}:\frac{9}{16}$
Multiply each ratio by 144 (LCM of 9 and 16)
$\therefore$ The required ratio = 64 : 81
Hence, the correct answer is 64

Correct Answer: 229

Solution : Given:
