A Single Point Urban Interchange moves more traffic through a smaller amount of space. Compare the Single Point to the Cloverleaf design, which takes up a much greater amount of land. The Single Point design makes it easier to build new interchanges within existing state property.
A cent is one hundredth of a dollar (in fact, the word cent is from a Latin word meaning hundred). So no, one tenth of a penny is not one hundredth of a dollar. 36 cents equals how many hundredths of dollars? 1 cent is 1 hundredth of a dollar so 36 cents are 36 hundredths of a dollar.
A million is a thousand thousand. So a million dollars is 1,000,000. Each dollar is about 45 rupees. So a million dollars are 45x1,000,000, which is 45,000,000. Or simply 45 million rupees. If you want to read this in the Indian system of lakhs and crores, then it is 4.5 crores.
