Questions seems to be incomplete
but we can surely determine the ratio here
suppose
no. of pencils sold = x
no. of pens sold = y
equate the average now
(2x + 3y)/(x+y) = 2.6
=> 2x + 3y = 2.6x + 2.6y
=> .4y = .6x
=> x/y = 2/3

1/31+1/32+1/33 = 1/10(1/3.1+1/3.2+1/3.3) Since (1/3+1/3+1/3)=1, (1/3.1+1/3.2+1/3.3)= slightly smaller than 1 Hence 1/10(1/3.1+1/3.2+1/3.3) ~= slightly smaller than 1/10 hence, 1/n>=1/10 or n<=10 lets consider the next no. n+1<=11 1/11=1/11(1/3+1/3+1/3)=(1/33+1/33+1/33) which is slightly smaller than...
