pav-90 [236]

Answer:

The correct answer is option (d).

A certain salesman's yearly income is determined by a base salary plus a commission on the sales he makes during the year. Did t
kiruha [24]

Given: {Income} = {salary} + {commission}. Question basically asks: is {salary} > {commission}?

(1) If the amount of the commission had been 30 percent higher, the salesman's income would have been 10 percent higher last year:

1.1({salary} + {commission}) = {salary} + 1.3{commission};

{salary} = 2{commission};

Therefore, {salary} > {commission}. Sufficient.

(2) The difference between the amount of the salesman's base salary and the amount of the commission was equal to 50 percent of the salesman's base salary last year:

|{salary} - {commission}| = 0.5{salary}, notice that {salary} - {commission} is in absolute value sign ||, meaning that we can have two cases:

A. {salary} - {commission} = 0.5{salary};

0.5{salary} = {commission};

{salary} > {commission}, thus the answer would be YES;

Or:

B. {commission} - {salary} = 0.5{salary};

1.5{salary} = {commission};

{salary} < {commission}, thus the answer would be No.

Two different answers. Not sufficient.

Answer: A.

Hope it's clear.

The rabbit population in a certain area is 500% of last years population. There are 900 rabbits this year. How many were there last year?

we know that

900 rabbits represent 500% of last year population

Last year population represent 100%

so

using proportion

Find out how many rabbits represent a percentage of 100%

\frac{900}{500\%}=\frac{x}{100\%}\\\\x=900(100)/500\\\\x=180\ rabbits
