floor of a building consists of 2000 tiles which are rhombus shaped and each of
its diagonals are
70 cm and 0.5 m in length. Find the cost
of polishing the floor, if the cost per sq. m. is Rs 12.50.
21. A
loaded truck travels 14 km in 2 litres of diesel. How many litres of diesel is
required for the truck to
