in a journey of 48 km perfomed by tonga, rikshawa and cycle that order the distance covered by the three ways in that order are in the ratio of 8:1:3 and charges per kilometer in that order are in the ratio of 8:1:4 if tonga charges being 24 paisa per kilometer the total cost of journey is ?

Solution(By Examveda Team)

Total distance covered = 48km
Distance covered ratio by Tonga, Rikshawa and Cycle is 8 : 1 : 3
∴ distance cover by Tonga = 8/12 * 48 = 32 KM
∴ distance cover by Rikshawa = 1/12 * 48 = 4 KM
∴ distance cover by Cycle = 3/12 * 48 = 12 KM

Charges per kilometer ratio by Tonga, Rikshawa and Cycle is 8 : 1 : 4
Given,Tonga charges being 24 paisa per kilometer
∴ Rikshawa charges per KM = 24/8 *1 = 3 paisa
∴ Cycle charges per KM = 24/8 *4 = 12 paisa

Total charge will be = 32*24 + 4*3 + 12*12 = 768 + 12 + 144
= 924 Paisa
= Rs. 9.24
