The given table shows the average temperature of some cities of India in a particular month.

City Average maximum temperature Average minimum temperature
New Delhi $39^oC$ $27^o$
Mumbai $36^oC$ $19^oC$
Ahemdabad $37^oC$ $19^oC$
Chennai $42^oC$ $26^oC$
Kolkata $38^oC$ $24^oC$

Which city has the highest difference its average maximum temperature and average minimum temperature?

  1. Kolkata

  2. Mumbai

  3. Chennai

  4. Ahemdabad
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Highest difference of arg maximum temperature & arg minimum temperature.

New Delhi = $39^{\circ}-27^{\circ}=12^{\circ}C$

Mumbai = $36^{\circ}-19^{\circ}=17^{\circ}C$

Ahmadabad = $37^{\circ}-19^{\circ}=18^{\circ}C$

Chennai = $42^{\circ}-26^{\circ}=16^{\circ}C$

Kolkata = $38^{\circ}-24^{\circ}=14^{\circ}C$

$\therefore $ Highest difference = $18^{\circ}C$ in city Ahmadabad.

The maximum temperature on a day is 35$^o$C and the minimum temperature is 25$^o$C. The difference of these temperatures, on Fahrenheit scale is

  1. 25$^o$F
  2. 75$^o$F
  3. 50$^o$F
  4. 100$^o$F
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

$35^oC- 25^o C = 10^oC$
$10^o C = \displaystyle \left( 10 \times \frac{9}{5} \right ) + 32$
$= 18 + 32 = 50^o F$.

The temperature at Bar Harbor, Maine, was $-3^{o}$ F. It then dropped during the night to
be $4$ times as cold. What was the temperature then?

  1. $12^{o}$ F
  2. $-12^{o}$ F
  3. $16^{o}$ F
  4. $-16^{o}$ F
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Since the temperature is $4$ times as cold.

$\therefore $  Temperature then was $4\times -3= -12^o $ F
