Andrea's recommended daily intake of potassium is 50% greater than that of her two-year-old brother. What is the least possible age, in years, of Andrea?
The correct answer is: 9
Her brother is 2 years. So, the intake will be 3000
50% greater than 3000 = 1.5 × 3000 = 4500 & it is for 9 – 13 years
Least possible age can be 9 years
