Question

If the temperature starts at -4°C, rises by 4°C, falls by 3° C and then rises again by 6°C, then what would be the final temperature?

Answer 1

The temperatures of the cities are as follows : Lahulspiti : –8°C; Srinagar : – 2°C; Shimla : 5°C; Ooty : 14°C; Bangalore : 22°C
(B) Temperature at the hottest place, i.e., Bangalore= 22°C
Temperature at the coldest place, i.e., Lahulspiti= – 8°C.
\ Temperature difference = 22° – (–8°C) = 30°C
(C) Temperature at Lahulspiti = – 8°C; Temperature at Srinagar = – 2°C
\ Temperature difference = – 2°C – (–8°C) = 6° C
(D) Temperature at Srinagar = – 2°C; Temperature at Shimla = 5°C
Temperature of Srinagar and Shimla taken together = – 2°C + 5°C = 3°C
Hence, the temperature of Srinagar and Shimla taken together is less than the temperature of Shimla but greater than the temperature of Srinagar.

Answer 2

-4 +4 -3 +6

= 3

final temperature is 3
