Question

The average of 5 numbers is 10,the number which should be added to make average is 12

Answer 1

Answer:

22

Step-by-step explanation:

let us take the 5 numbers as A,B,C,D,E

SO AVG=A+B+C+D+E/5=10,

               A+B+C+D+E=50

AND let us take the other number as X

  so,    AVG=A+B+C+D+E+X/6=12

WE KNOW THAT A+B+C+D+E=50

  SO 50+X/6=12

         50+X=72

           X=22

THERE FORE,, THE REQUIRED NUMBER IS 22 TO MAKE THE AVERAGE 12
