 A calorie is a unit of energy, specifically used to measure heat energy.

1 calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C.

In dietary terms, we use kilocalories (kcal) — where 1 kcal = 1000 calories — but it still measures energy, not diet or food itself

Explanation

Aristotle is widely considered the founder of meteorology.

He first used the term "meteorology" in the fourth century BC, although his work on weather was based on observation and lore rather than modern scientific methods.

Explanation

Let the total number of rabbits = x

Let the total number of pigeons = y

total number of head = 20 

                x + y = 20        eq (1)

total number of feet = 48 

             4x  +2y  = 48

              2x + y   = 24    eq (2)

Subtracting equation (2) from eq (1)

   2x + y -x - y = 24 -20

        x = 4

Explanation

Let the cost of 1 chair be Rs. x and the cost of 1 table be Rs. y.

From the first set of values, we get: 3x + 2y = 700 ... (i)

From the second set of values, we get: 5x + 3y = 1100 ... (ii)

Multiply equation (i) by 5: 15x + 10y = 3500 ... (iii)

Multiply equation (ii) by 3: 15x + 9y = 3300 ... (iv)

Subtract equation (iv) from equation (iii): y = 200

Substitute y = 200 in equation (i): 3x + 2(200) = 700 => 3x = 300 => x = 100

Finally, find the cost of 2 chairs and 2 tables: 2x + 2y = 2(100 + 200) = Rs. 600
