The Native American population in state A and B is 282,000 and 94,000 respectively.
Here, we are given that State A's population of Native Americans is three times the Native American population of State B.
Let the Native American population in state B be x
Thus, the Native American population in state A will be 3x
Total Native American population in state A and B = 376,000
Thus, we can get the following equation-
x + 3x = 376,000
4x = 376,000
x = 376,000/ 4
x = 94,000
⇒ 3x = 3 × 94,000
3x = 282,000
Thus, the Native American population in state A and B is 282,000 and 94,000 respectively.
