Question

A person travelled $\frac{5}{8}$th of the distance by train $\frac{1}{4}$th by bus and the remaining 15 km by boat .The total distance travelled by him was

• A. $90$ km
• B. $120$ km
• C. $150$ km
• D. $180$km

Answer 1

The correct option is B $120$ km

Let total distance be x km
$x-(\frac{5x}{8}+\frac{x}{4})=15$
$x-\frac{7x}{8}=15$
x = 120 km
