Question

The average of 5 positive integers is 436. The average of the first two numbers is 344 and the average of the last two numbers is 554. What is the third number ?

Answer 1

The third number is 384

Answer 2

Answer:

384

Step-by-step explanation:

sum of  numbers= average * number of numbers

sum of   5 positive integers =436 *5 =2180

sum of first two numbers   =344 *  2  =688

sum of last   two numbers   = 554 * 2 =1108

  third number = sum of   5 positive integers -(sum of first two numbers + sum of last   two numbers)

                        =2180-(688+1108)

                        =2180-1796

                         =384
