Answer:
100% - (45% + 27%) = 28% = 2940
100 = 2940/28 × 100 = 105 × 100 =10500
Alternative method,
Let the total population be x.
The business people = x × 45/100 = 45x/100
Teachers = x × 27/100 =27×/100
According to the Question,
x - (45x/100 + 27x/100) = 2940
× - 72x/100 = 2940
100x/100 - 72x/100 = 2940
28x/100 = 2940
x = 2940 × 100/28 = 10500
