# The present ages of A and B are as 6 : 4. Five years ago their ages were in the ratio 5: 3. Find their present ages.

Ans: 30, 20

Go from the choices
Choice (3) 30 and 20 are in the ratio of 6: 4
Five years ago their ages would be 25 and 15 which are in the ratio 5 : 3.
Hence choice (3) is the right answer.

# A trader makes a profit equal to the selling price of 75 articles when he sold 100 of the articles. What % profit did he make in the transaction?

Ans: 300%

Let S be the selling price of 1 article.
Therefore, the selling price of 100 articles = 100 S. --(1)
The profit earned by selling these 100 articles = selling price of 75 articles = 75 S -- (2)
We know that Selling Price (S.P.) = Cost Price (C.P) + Profit -- (3)
Selling price of 100 articles = 100 S and Profit = 75 S from (1) and (2). Substituting this in eqn (3), we get
100 S = C.P + 75 S. Hence, C.P = 100 S - 75 S = 25 S.
Profit % = 300%

# An analysis of the monthly incentives received by 5 salesmen: The mean and median of the incentives is $7,000. The only mode among the observations is $12,000. Incentives paid to each salesman were in full thousands. What is the difference between the highest and the lowest incentive received by the 5 salesmen in the month?

Ans: $ 11,000

The arithmetic mean of 5 observations is $7000.
Therefore, the sum of these 5 observations is 5 * 7000 = $35,000.
The median is $7000.
Let us say their incentives in ascending order are a, b, c, d and e.
So, c = 7000 and a + b + c + d + e = $35,000
The only mode is $12,000. So, the maximum number of observations among the 5 will be in $12,000.
The only possibility is that both d and e got an incentive of $12,000 each.
So, c + d + e = 7000 + 12000 + 12000 = $31,000
Therefore, a + b = 35,000 - 31,000 = 4000.
a and b have to be two different values as the only mode is $12,000.
So, a has to be $1000 and b has to be $3000.
The difference between the highest and the lowest is therefore 12,000 - 1000 = $11,000
