We are given that the revenue from the sales of jazz and blues in 2000 accounted for 0.06 x (840 million) = 50.4 million dollars in revenue. We need to determine the revenue from the sales of jazz and blues in 1998.

Statement One Alone:

Jazz and blues recordings accounted for 5 percent of the revenue from the sales of recordings in Country Y in 1998.

Since we do not have any information about the total revenue in 1998, statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.

Statement Two Alone:

The revenue from the sales of jazz and blues recordings in Country Y increased by 40 percent from 1998 to 2000.

Using the information given and statement two, we can determine the revenue from sales of jazz and blues in 1998. If we let the revenue from sales of jazz and blues in 1998 = R, we can create the following equation:

1.4R = 50.4 million

R = (50.4 million)/1.4

R = 36 million

Statement two alone is sufficient to answer the question.

Answer: B

(2) The revenue from the sales of jazz and blues recordings in Country Y increased by 40 percent from 1998 to 2000

we get .06*840mil = 50.4 mill in 2000 revenue.
from stmt 2, we get in 1998, revenue = .6 *50.4

B is the answer.

(1) Jazz and blues recordings accounted for 5 percent of the revenue from the sales of recordings in Country Y in 1998:

We dont know the revenue from the sale of recordings in 1998 and cant calculate revenue from jazz and blues recordings. INSUFFICIENT

(2) The revenue from the sales of jazz and blues recordings in Country Y increased by 40 percent from 1998 to 2000

Revenue in 2000 = $50.4 million
Let revenue in 1998= x

x + 0.4 * x =$50.4
x=$36 million

SUFFICIENT

Ans:B

Focusing on the relationship of variables helps to see sufficiency in percentage DS questions. Often they can confuse you to think you have info or more than often you don't have enough information.

Stem gives us 2000 Revenue = .06 * 840 Million

We require revenue in 1998 by jazz & blues
Statement 1 : Gives us Revenue Percentage of 1998 with no amount of that year. Insufficient
Statement 2 : Gives us increase in Revenue from 1998 to 2000. Which translates to => x + .4x = .06 * 840 Million. Sufficient

From statement 2 alone we can get x ( revenue of 1998)

Hence Answer is B.

Writing down what is required clearly on paper, will help a lot in terms of recognizing what relationship you need for sufficiency.
Further breaking that down ahead increases accuracy.

i HAVE A DOUBT IN ANSWER. CAN ANYBODY CLARIFY.
In question 6% of revenue is given in year 2000 but in year 1998 the % of revenue is not mentioned.

How do we assume it is fixed 6% while opting a choice B. This percentage may also change in the year 1998.

maddyjss we know that 6 % of $840 is 50.4. So revenue in 2000 was 50.4.


As per second statement we are told revenue from 1998 to 2000 rose by 40% .

Now do you see relationship between revenue in 1998 and 2000 ? :-)

So we can create an equation based on the information below.

Revenue in 2000 is 50.4

Let revenue in 1998 be Y, Hence increase of revenue from 1998 to 2000 can be expressed like this y+0.40y i.e. 1.40

1.40y = 50.4

y = 36

hope it helps :)
