Answer:
Option (A) 1 : 2
Step-by-step explanation:
Let the revenue from cars in 1996 be 'x'
and revenue from trucks in 1996 be 'y'
Therefore,
total revenue in 1996 = x + y
According to the question:
In 1997
Total revenue = ( 100% - 11% )x + (100% + 7%)y
= 0.89x + 1.07y ..............(1)
Also,
Total revenue in 1997 = ( 100% + 1%)( x + y )
= 1.01( x + y ) ...........(2)
equating 1 and 2
0.89x + 1.07y = 1.01( x + y )
or
0.89x + 1.07y = 1.01x + 1.01y
or
0.06y = 0.12x
or
![\frac{x}{y}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B1%7D%7B2%7D)
Hence,
Option (A) 1 : 2
