Verified Answer
The revenues and expenditures of companies X and Y are in the ratio 8 ...
Let the revenue of X and Y (in Rs. lakhs) be 8x and 9x respectively.
Let the expenditure of X and Y (in Rs. lakhs) be 14y and 16yrespectively.
8x - 14y = 9x - 16y.
x = 2y Also, 8x - 14y = 16.5; 16y-14y= 16.5 2y= 16.5
Revenue of X = 8x = 8 * 2y = 8 x 16.5 = Rs. 132 lakhs And, expenditure of Y = 16y = 8 * 2y = 8 x 16.5 = Rs. 132 lakhs
Hence, option 1.
