Correct Answer - Option 4 : 130 km
Given
A man covers 3/5 of the total journey by rail, 7/20 by bus and remaining 6.5 km by foot
Calculation
Let the total journey be 100x km
⇒ He covers 3/5(100x) by rail
⇒ He covers 60x km by rail
⇒ 7/20(100x) km by bus
⇒ 35x km by bus
⇒ Remaining journey = 100x - (60x + 35x)
⇒ Remaining journey = 5x
⇒ 5x = 6.5 ( which he covers by foot)
⇒ 100x = 130 km
∴ The total journey is 130 km
