A certain meter records voltage between 0 and 10 volts inclusive. If the average value of 3 recordings on the meter was 5 volts, what was the smallest possible recording in volts?  Options
A) 2  B) 3  C) 4  D) 5  E) 6
if average of 3 is 5 so sum of 3 should be 15   3 recording can be from 0-10 inclusive   to find one smallest other two should be highest   so, lets assume three var are a,b,c   say a is smallest and give b and c greatest readings say 6 and 6   so a has to be 3   3
