Question

If 2 times an integer x is increased by 5, the result is always greater than 16 and less than 29. What is the least value of x?

Answer 1

The least value of x is 6 .

According to the question ,

16 < 2x + 5 < 29

Hence , if we take 5 as x then ,

2 * 5 + 5 = 15

So , x = 5 is wrong because 15 is smaller than 16 ,

Now ,let we take x = 6 ,

Then , 2*6 + 5 = 17

hence six is the least number .
