Maiya has two sisters. The first sister is twice as old as Maiya. The first sister is 1 year younger than Maiya. Their average age is 5. How old is Maiya?
Their total age is 15 because 3 x 5 = <<3*5=15>>15
15 - X - 2X -(X-1) is equivalent to 16 = 4X
Maiya is 4 years old because 16 / 4 = <<16/4=4>>4
