To find:
Two consecutive natural numbers whose sum is 75
Step-by-step explanation:
Here the sum is 75
Now 75 ÷ 2 = 37.5, but it is not a natural number.
Let us take (37.5 - 0.5) and (37.5 + 0.5) instead, that is 37 and 38. They are natural numbers.
Also 37 + 38 = 75
Answer: The consecutive natural numbers are 37 and 38.
We can find the solution in another way.
Let the two consecutive natural numbers be x and x + 1.
Then x + x + 1 = 75
⇒ 2x + 1 = 75
⇒ 2x = 74
⇒ x = 37
Then x + 1 = 37 + 1 = 38
Answer: The required numbers are 37 and 38.
