The monkey is descending
 
let m be mass of monkey
 
T be tension
 
a be acceleration
 
So
 
mg - T = ma
 
Now here breaking strength is given that is maximum tension
 
As mg - T = ma
 
So if T is maximum and u are subtracting it with mg it would give least value of ma that is minimum acceleration
 
T = 75 % of mg
 
so mg - 75% of mg = ma
 
25% of mg = ma
 
mg/4 = ma
 
g/4 = a
