A, B and C started a business with capitals of Rs. 8000, Rs. 10000 and Rs. 12000 respectively. At the end of the year, the profit share of B is Rs. 1400. The difference between the profit shares of A and C is? | [
"441",

Let the required actual distance be x km
More scale distance, More actual distance(direct proportion)
Hence we can write as
scale distance.6:80.5}::6.6:x
