Question 95
A swimming pool is 20m long 15m wide and 3m deep. What will be the cost of repairing the floor and wall of the pool at the rate of Rs.25 per square metre ?
Solution
Total surface area to be painted = (15×20)+2(15×3)+2(20×3)= 510 $$m^2$$
Hence, the cost incurred = 510*25= Rs. 12750
Therefore, option C is the correct answer.
