Vinay Sipani    11 years AGO

sum of 5 numbers = 35*5 = 175 ------(1)
sum of 7 numbers = 25*7 = 175 ------(2)

=> sum of two numbers = equ(2) - equ(1) = 0

average of 5 numbers is 35 ( sum = 25*5=175) and average of 7 numbers (2 new numbers are added) is 25 ( sum = 25*7=175). Sum of the 2 newly added numbers will be 175-175=0.

Let the sum of 5 numbers be x,
x/5=35
then, x=175.

Now let the two numbers be y and z,
(x+y+z)/7=25
x+y+z=175
Now, put the value of x,
175+y+z=175
y+z=0

given
(x1+x2+x3+x4+x5)/5=35.->x1+x2+x3+x4+x5=175
now
(x1+x2+x3+x4+x5+x6+x7)/7=25->175+x6+x7=175
which gives x6+x7=175-175=0

a+b+c+d+e/5=35
a+b+c+d+e=175....i)
a+b+c+d+e+f+g/7=25
a+b+c+d+e+f+g=175....ii)
putting the value of i) equation in ii)
we get:
175+f+g=175
f+g=0
so correct option is 9)0

5 numbers average is 35, if we average that sum with 7 numbers we will get 25 as average so additional two number's sum is zero(o)

Avg of 5 numbers = 35 then sum =35*5 =175;
Avg of 7 numbers = 25 then sum =25*5 =175.
both sum are same. so, added 2 new numbers must be 'ZERO'
