Some information is missing. 
The value of load is not mentioned. 
Below is the hint which can be inferred from the available data. This will help you to solve the problem. 
The MA >1 Thus, effort arm > load arm 
The lever will act as force multiplier as MA>1. Thus, effort required to lift the load will be less than the value of the load. 
MA = Load(L)/Effort(E) = Effort arm / Load arm
