Lan is 146 centimeters tall now.
<u><em>Explanation</em></u>
Let, Lan's current height is centimeters
As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = centimeters and Jim's current height = centimeters.
Every month, their heights increase by 2 centimeters.
So, after 5 months.....
Lan's height = centimeters,
Lisa's height = centimeters and
Jim's height = centimeters
Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....
So, the current height of Lan is 146 centimeters.
