# CAT Quant Practice Problems

Question: For these questions the following functions have been defined.

$\begin{array}{l}{\rm{la}}\left( {x,y,z} \right) = \min \left( {x + y,y + z} \right)\\{\rm{le}}\left( {x,y,z} \right) = \max \left( {x - y,y - z} \right)\\{\rm{ma}}\left( {x,y,z} \right) = \frac{1}{2}\left[ {{\rm{le}}\left( {x,y,z} \right) + la\left( {x,y,z} \right)} \right]\end{array}$

For x = 15, y = 10 and z = 9, find the value of le(x, min(y, x − z), le(9, 8, ma(x, y, z))).
