Answer & Solution
Correct Answer:
Option
C
The man covers $$\frac{9}{20}$$ of the journey by bus
∴ Remaining journey :
= 1 - $$\frac{9}{20}$$
= $$\frac{11}{20}$$
⇒ According to the question,
$$\frac{11}{20}$$ of the journey :
= $$\frac{20}{11}$$ × 10
= 18.18 km
∴ Remaining journey :
= 1 - $$\frac{9}{20}$$
= $$\frac{11}{20}$$
⇒ According to the question,
$$\frac{11}{20}$$ of the journey :
= $$\frac{20}{11}$$ × 10
= 18.18 km
