9.A man enquires a person about the past 5 days temperatures at 12 noon in that region. The other replies that he doesn\'t remember the actual figures but there was a different temperature on each day and that their product gives 12. Assuming the temperature to the nearest degree what are the temperatures on the five days?
Ans: -1,-2,1,2,3
Approach:
We know that the smallest two integers that can give a product of 12 is 3*4 which is spilt up as 2*2*3. But no temperature is the same...hence use -2 instead of 2. Now the product becomes -12. Choose the other temperatures such that value of the product does not change but only the sign changes. So naturally, the other two options are -1 and 1.
10.One eight mark question.
