Official Explanation

2. If there are 20,000,000 females aged 15–25, then how many females aged 15–25 (in millions) watch neither Blonde Fury nor Hart Attack?

Email #1 describes the company’s plan to increase revenue by ramping up advertising to females aged 15−25. Email #2 identifies the two most popular programs among females aged 15−25. Memo #1 presents advertising and viewership data for the two programs.

According to Memo #1, 45% of females aged 15−25 watch Blonde Fury and 35% of females aged 15−25 watch Hart Attack. If there are 20,000,000 females aged 15−25, then 0.45 × 20,000,000 = 9,000,000 watch Blonde Fury, and 0.35 × 20,000,000 = 7,000,000 watch Hart Attack.

According to Email #2, 80% of female viewers aged 15−25 who watch Hart Attack also watch Blonde Fury. If 7,000,000 females aged 15−25 watch Hart Attack, then 0.80 × 7,000,000 = 5,600,000 who watch Hart Attack also watch Blonde Fury.

Use the group formula to answer the question, group 1 + group 2 + neither –both = total. Substitute the calculated values into the formula, so that 7,000,000 + 9,000,000 + neither – 5,600,000 = 20,000,000. Simplify the equation, so that neither = 9,600,000.

The correct answer is (D).

Can you explain why the answer of Q1 first part is NO?

It is said that Female (15-25) is our top consumer for the programs. So if any other age group or any other group watch more frequently than this one then how can be female (15-25) be top consumer?

We can infer that among females aged 15–25, Blonde Fury and Hart Attack are the two most watched programs. However, we cannot conclude that no other group watches these programs more frequently than this group. So, no other program is more popular among females aged 15–25, but we don’t know whether these two programs are watched even more by some other groups.

For C of 1st question, we can actually calculate and negate this. Even though we just know the % but base of both is same so it is possible to calculate the raio?

The answers for Question 1 are:
1) NO (The data present doesn't talk about any other gender or age group)
1) NO (The data doesn't talk about how expensive the ads are based on their run time.)
1) NO (We know the percentage of women and not their exact number, this data is also un inferable.)

The answer for Question 2 is:
20 * 0.45 + 20 * 0.35 - 20 * 0.35 * 0.8 - x = 20
x = 9.9
Option D


The answer for Question 3 are:
1) YES (the first mail shows that this strategy has succeeded 3 times before.)
2) YES (the First mail shows that this strategy did lead to an increase in revenue all the 3 times it had been used before.)
3) YES (Can be inferred from the first mail.)

You cannot calculate that ratio. The data gives only the percentage of viewers and the cost per ad, not the total money spent, so the statement cannot be confirmed.
