79 - Leo can buy a certain computer for p1 dollars in state A, where the sales tax is t1 percent, or he can buy the same computer for p2 dollars in state B, where the sales tax is t2 percent. Is the total cost of the computer in State A than is State B?

(1) t1 > t2

(2) p1 t1 > p2 t2

note: Is there any other way other way to solve the this without using too much algebra a simpler way. It toke too much time just to figure out the problem then prove if it is sufficient or not? Perhaps picking numbers ??






87- Is then number of seconds required to travel d1, feet at r1 feet per second greater than the number if seconds required to travel d2 feet at r2 feet per second?

(1) d1 us 30 greater than d2

(2) r1 is 30 greater than r2


Note: Is the questions asking determine if d1/r1 is greater than d2/r2 ???? and how would you solve it if want to use picking number as simpler way to solve both statements. Please provide step-by- step instructions.

Hi There,

Solution: Statement 1) is not sufficent because we do not know any thing about P1
Statement 2) is again not sufficient because we are getting yes/ no combination
Explaination: Take P1 : $ 100 and T1 : 11 % total cost is $ 110
Take P2 : $ 50 and T2 : 10% then total cost will be $55 Yes combination
Take P1 : $ 500 and T1: 100% total cost $ 1000
Take P2: $1000 and T2 : 11% total cost will be $ 1110 No combination
We are not getting unique answer from Statement 2 also.

Now If we combine both the statement again we will get Yes/ no combination (check with same numbers as stated above), so answer is E (I hope)

In this kind of question please also check with Extreme values.

I hope this will help

If you do not mind asking...

Can you tell me what is the question really asking please??
In statement (2) it said P1 t1 > P2 t2. So why do you make P2 = 1000 and t2 = 11%. In a yes/no question don't you use the statement to answer the question. you're not trying to disprove the statement???

Hi There,

That's a good question

I am not disapproving any thing, regarding statement 2 with some combination of numbers we are getting P1>P2 that's Yes combination and with other sample we are getting P1<P2 means no combination, so it means 2nd statement alone is not sufficient to get the unique answer.

I hope this will help.

Thanks
