A certain meter records voltage between 0 and 10 volts inclusive. If the average value of 3 recordings on the meter was 4 volts, what was the smallest possible recording in volts?	Choose the correct choice.
A) 2  B) 3  C) 4  D) 5  E) 6

Rationale: if average of 3 is 4 so sum of 3 should be 12 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 5 and 5 so a has to be 2 a
Answer: A
