1)  

 The temperature in ooty was 20°C on Monday, 10°C on Tuesday, and 7°C on Wednesday. Which list shows the days from coolest to warmest





Answer: 4


SOLUTION 1 :

Slove:

7 is the smallest of the three numbers, so 7°C is the coolest.

20 is the largest number, so 20°C is the warmest.

Since 7°C is the coolest and 20°C is the warmest, 10°C must be in between.

So, the list from coolest to warmest is Wednesday, Tuesday, Monday.



2)  

Madurai recorded a temperature of Thirty Six degrees Celsius, and Selam recorded a temperature of Twenty Five degrees Celsius. Who recorded a warmer temperature



Answer: 2



SOLUTION 1 :

Solve:

36°C is warmer than 25°C. So, Madurai recorded a warmer temperature.



3)  

Chennai recorded a temperature of Thirty Seven degrees Celsius, and Kovai recorded a temperature of Thirty degrees Celsius. Who recorded a cooler temperature



Answer: 1



SOLUTION 1 :

Solve:

Thirty Celsius is cooler than Thirty Seven degrees Celsius. So, Kovai recorded a cooler temperature.



4)  

 At 4:00 AM, the temperature is 12°C. If the temperature drops 2°C per hour, what will the temperature be at 7:00 AM

Answer: 6 °C


SOLUTION 1 :

Solve:

The temperature drops 2°C for 3 hours, so multiply 3 times:

2 x 3 = 6

Subtract the starting temperature 

12 - 6 = 6

So, the temperature will be 6°C.



5)  

 The temperature went down 2 degree Celsius and then down 4 degrees Celsius, ending up at a final temperature of  -17 degrees Celsius. What was the starting temperature

- Answer: 11 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-17°C + 2°C + 4°C = -11°C

So, the starting temperature was -11 degrees Celsius.



6)  

 The temperature in ooty was 20°C on Monday, 11°C on Tuesday, and 7°C on Wednesday. Which list shows the days from coolest to warmest





Answer: 4


SOLUTION 1 :

Slove:

7 is the smallest of the three numbers, so 7°C is the coolest.

20 is the largest number, so 20°C is the warmest.

Since 7°C is the coolest and 20°C is the warmest, 11°C must be in between.

So, the list from coolest to warmest is Wednesday, Tuesday, Monday.

45°C is warmer than 28°C. So, Madurai recorded a warmer temperature.



8)  

Chennai recorded a temperature of Forty Three degrees Celsius, and Kovai recorded a temperature of Thirty degrees Celsius. Who recorded a cooler temperature



Answer: 1



SOLUTION 1 :

Solve:

Thirty Celsius is cooler than Forty Three degrees Celsius. So, Kovai recorded a cooler temperature.



9)  

 At 6:00 AM, the temperature is 12°C. If the temperature drops 1°C per hour, what will the temperature be at 11:00 AM

Answer: 7 °C


SOLUTION 1 :

Solve:

The temperature drops 1°C for 5 hours, so multiply 5 times:

1 x 5 = 5

Subtract the starting temperature 

12 - 5 = 7

So, the temperature will be 7°C.



10)  

 The temperature went down 3 degree Celsius and then down 4 degrees Celsius, ending up at a final temperature of  -19 degrees Celsius. What was the starting temperature

- Answer: 12 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-19°C + 3°C + 4°C = -12°C

So, the starting temperature was -12 degrees Celsius.
