(a)2 : 1
(b)5 : 6
(c)6 : 5
(d)Data inadequate
(e)None of these
Answer
Answer (as printed): C
Explanation
Let breadth be $x$ metres. Then, length $=120 \%$ of $x=\left(\frac{120}{100} x\right)=\frac{6 x}{5} \mathrm{m}$. $$\text { Required ratio }=\left(\frac{6 x}{5} \times x \times \frac{1}{x \times x}\right)=6: 5 .$$
