Dear student,


Petrol is consumed on the basis of distance covered. First find the distance covered by both the cars.


Use distance= speed*time

distance travelled by car A = distance travelled by car B = 400Km


petrol required to travel X km = 1L for car A


pertrol required to travel X+5 km = 1L for car b


1L = X+5 km


1km = 1/ X+5


petrol required for B to travel 400km = 400/X+5


petrol required for A to travel 400km = 400/X


given that


400/X - 4 = 400/X+5


(400-4X)/X = 400/ X+5


(400-4X)(X+5) = 400 X -----------------------BY CROSS MULTIPLICATION


now solve the equation, you will get two answers .


the negative answer is omitted and the positive answer is taken as the petrol consumed by car A


add 4 to it and you will get the petrol consumed by car B
