Answer 1

(1)

Here, we have to select a number from 1 to 10.

The perfect number that satisfies the condition is 2.

Square of 2 is 4

Cube of 2 is 8 - Double the square of number(4 * 2).

Therefore, the number john is thinking of is 2.

(2)

Given that the temperature at the midday was 14 degree Celsius.

Given that it had fallen by 17 degree Celsius.

So, the temperature at midnight = (14 - 17) = -3 degree Celsius.

Hope this helps!
