1.	The following table gives the daily income of ten workers in a factory. Find the arithmetic mean. {:("Workers",A,B,C,D,E,F,G,H,I,J),("Daily Income(in Rs.)",120,150,180,200,250,300,220,350,370,260):}
Answer» Solution : `{:("Workers",,"Daily INCOME (in Rs.)"),(,,""(X)),(""A,,""120),(""B,,""150),(""C,,""180),(""D,,""200),(""E,,""250),(""F,,""300),(""G,,""220),(""H,,""350),(""I,,""370),(""J,,""260),(,,""sumX="2,400"):}` `barX=(sumX)/N=(X_(1)+X_(2)+...X_(10))/10` `=(2,400)/10=240` `:. "Arithmetic mean "Rs. 240.`
