Study the following information carefully and answer the questions. For a room, the rate of painting is Rs. 3200 per square metre. The rate of carpeting per square metre is 120% of that of tiling. The cost of decorating the room is 14 times to that of carpeting on the floor. The cost of electrification is 75% of that of carpeting the floor. The rate of tiling on the floor is 125% of that of painting. The dimensions of the room are 6m $\times$ 6m $\times$ 5m. What is the ratio of the cost of painting the four walls of the room and that of decoration? 

Answer & Explanation
Answer : Option
A


Explanation : 

Rate of painting per sq.metre = Rs. 3200 Rate of tiling per square metre = ${3200 \times 125} \over 100$ = Rs.4000 Rate of carpeting per sq.metre = ${400 \times 120} \over 100$ = 4800
