Answer:
Rs. 800
Step-by-step explanation:
Since Distance travelled by car ,bus, bike are in the ratio 4:3:2 let There distances be 4x km , 3x km ,2x km respectively.
Since Cost by car ,bus, bike are in the ratio 1:2:4 let Their actual costs be y, 2y, 4y respectively.
Cost Spent for Car = 4x*1y
Cost Spent for Bus = 3x*2y
Cost Spent For Bike = 2x*4y
Total cost 3600 = 4xy + 6xy + 8xy
⇒3600=18xy
⇒xy=200
Cost Spent for car = 4xy = 4*200 = 800
Therefore, Cost spent for car = Rs. 800
