Question

A person travelled 5/8th of the distance by train, 1/4th by bus and the remaining 15 km by boat. What was the total distance travelled by him ?​

Answer 1

Answer:

$\huge\underline\bold {Answer:}$

Let the total distance travelled by him be x km.

Then, 5x/8 + x/4 + 15 = x

=> x – 5x/8 – x/4 = 15

=> $\frac{8x - 5x - 2x}{8} = 15$

=> x/8 = 15

=> x = 120 km

Therefore, total distance travelled by him = 120 km.
