A peculiar odor caught the author's attention one Sunday afternoon. Then he noticed smoke swiftly filling the room as it began to stream in through the ceiling's cracks. They hardly saw anything at all. The roof had caught fire and was rapidly spreading by the time they dashed into the front yard. His mother bolted back inside. She had produced a tiny metal box that contained numerous essential documents. One by one, she wanted to remove everything significant from the house. She was "crazed" at the time.
(Street Plan) : A city has two main roads which cross each other at the centre of the city. These two roads are along the North-South direction and East-West direction.
All the other streets of the city run parallel to these roads and are 200 m apart. There are 5 streets in each direction. Using 1cm = 200 m, draw a model of the city on your notebook. Represent the roads/streets by single lines. There are many cross- streets in your model. A particular cross-street is made by two streets, one running in the North - South direction and another in the East - West direction. Each cross street is referred to in the following manner : If the 2nd street running in the North - South direction and 5th in the East - West direction meet at some crossing, then we will call this cross-street (2, 5). Using this convention, find:
(i) how many cross - streets can be referred to as (4, 3).
(ii) how many cross - streets can be referred to as (3, 4).
