Answer 2

Answer:

To find :- The average of 6 numbers

Solution :-

As per the 1st condition,

Sum of 1st three numbers is 36

( a + b + c ) = 36

As per the 2nd condition,

Sum of last three numbers is 64

( x + y + z ) = 64

Now,

Average = 1st three no.s + last three no.s / T. no.s

= ( 36 + 64 ) / 6

= 100 / 6

= 16.6
