A man covers `(2)/(15)` of the total journey by train, `(9)/(20)` by bus and the remaining 10km on foot. His total journey (in km) is

Options

A. 15.6
B. 24
C. 16.4
D. 12.8

Answer

B

Explanation

मानाकि कुल यात्रा x km है।
`x-x xx(2)/(15)-x xx(9)/(20)=10`
`impliesx-(2x)/(15)-(9x)/(20)=10`
`implies(60x-8x-27x)/(60)=10`
`implies25x=60xx10`
`impliesx=(600)/(25)=24km`
