###Human: How many apples did two men and three women buy at a certain store if the two men each bought 30 apples, 20 less than the number of apples bought by each woman?, ### Assistant: If the two men each bought 30 apples, together they bought 2*30 = 60 apples.
Since the two men each bought 30 apples, 20 less than the total number of apples bought by each woman, each woman bought 20+30 = 50 apples.
The total number of apples bought by the women is 3*50 = 150
Altogether, the two men and three women bought 60+150 = 210 apples. 
 So the answer is :  210
