Show Answer
Correct Answer: (5)
Solution: (5) Time Taking by Honda car
$=\frac{300}{260 \times 80 \%}=\frac{300}{26 \times 8}$
$\approx 1.44$ hours
Time taken by Hyundai
$=\frac{320}{140 \times 70 \%}=\frac{320 \times 100}{140 \times 70}$
$=3.27$ hours
Required percentage
$=\left(\frac{3.27-1.44}{3.27}\right) \times 100 \approx 56 \%$
