GIVEN: Janani is 6 centimeters taller than Preeti, who is 10 centimeters taller than Rey.
Let Rey's height = x
So, Preeti's height = x + 10
And Janani's height = x + 10 + 6 = x + 16
The average (arithmetic mean) height of the three people = (x + x+10 + x+16)/3
= (3x + 26)/3
= 3x/3 + 26/3
= x + 8.66666...
The three heights are x, x+10, and x+16
So, the MEDIAN height = x+10
We get:
QUANTITY A: x + 8.66666...
QUANTITY B: x + 10
Answer: B
