Answer» (a) The temperature of the places marked on it is:
(b) The temperature of the hottest place Bangalore = 22oC The temperature of the coldest place Lahulspiti = –8oC Difference = 22oC – (–8oC) = 22oC + 8oC = 30oC (c) The temperature of Srinagar = –2oC The temperature of Lahulspiti = –8oC Difference = –2oC + (–8oC) = –2oC –8oC = 6oC (d) The temperature of Srinagar and Shimla = 5oC + (–2oC) = 5oC –2oC = 3oC The temperature at Shimla = 5oC Therefore, 3oC < 5oC Thus, temperature of Srinagar and Shimla taken together is less than the temperature at Shimla. Now, Temperature of Srinagar = – 2oC Therefore, 3oC > –2oC No, it is not less than the temperature at Srinagar. |
