Answer & Solution
Answer: Option A
Solution:
$$\eqalign{
& 55\,\min .\,{\text{spaces}}\,{\text{are}}\,{\text{covered}}\,{\text{in}}\,60\,\min \cr
& 60\,\min .\,{\text{spaces}}\,{\text{are}}\,{\text{covered}}\,{\text{in}} \cr
& = \left( {\frac{{60}}{{55}} \times 60} \right)\,\min . \cr
& = 65\frac{5}{{11}}\,\min . \cr
& {\text{Loss}}\,{\text{in}}\,64\,\min . \cr
& = \left( {65\frac{5}{{11}} - 64} \right) = \frac{{16}}{{11}}\,\min . \cr
& {\text{Loss}}\,{\text{in}}\,24\,hrs. \cr
& = \left( {\frac{{16}}{{11}} \times \frac{1}{{64}} \times 24 \times 60} \right)\,\min. \cr
& = 32\frac{8}{{11}}\,\min. \cr} $$
