Question

Martiza remembers her pin because it is between 1000 and 1500 and it is a product of two consecutive prime numbers what is her pin

Answer 1

Her pin must be 1147

Explanation:

A little trick I have up my sleeve when I have these kind of questions is that I find the square root of each number, then find what is prime.

`√(1000)  = 31.6`

`√(1500) = 38.7`

Since the only prime numbers in the range of 31 and 38 is 31 and 37.

We can then multiply 31 by 37 to get 1147.
