Rounding Rules on the GMAT: Slip to the Side and Look for a   [#permalink]

### Show Tags

02 Jun 2014, 10:00
 FROM Veritas Prep Admissions Blog: Rounding Rules on the GMAT: Slip to the Side and Look for a Five! The famous rounding song by Joe Crone is pretty much all you need to solve the trickiest of rounding questions on GMAT:You just slip to the side, and you look for a five.Well if the number that you see is a five or more,You gotta round up now, that’s for sure.If the number that you see is a four or less,   You gotta round down to avoid a mess.To put it in our own words, when we round a decimal, we drop the extra decimal places and apply certain rules:-          If the first dropped digit is 5 or greater, we round up the last digit that we keep.-          If the first dropped digit is 4 or smaller, we keep the last digit that we keep, the same.For Example, we need to round the following decimals to two digits after decimal:(a) 3.857We drop 7. Since 7 is ‘5 or greater’, we are left with 3.86(b) 12.983We drop 3. Since 3 is ‘4 or smaller’, we are left with 12.98(c) 26.75463We drop 463. Since 4 is ‘4 or smaller’, we are left with 26.75(d) 8.9675We drop 75. Since 7 is ‘5 or greater’, we are left with 8.97Note example (c) carefully:When we round 26.75463 to two decimal places, we do not start rounding from the rightmost digit i.e. this is incorrect: 26.75463 becomes 26.7546 which becomes 26.755 which further becomes 26.76 – this is not correct. .00463 is less than .005 and hence should be ignored. You only need to worry about the digit right next to the digit you are keeping. Just slip to the side, and look for a five!A logical question arises: what happens when we have, say, 2.5 and we need to round it to the nearest integer? 2.5 is midway between 2 and 3. In that case, why do we round the number up, as the rule suggests? Note that a 2.5 is a tie and we have many tie breaking rules that can be used. They are ‘Round half to odd’, ‘Round half to even’, ‘Round up’, ‘Round down’, ‘Round towards 0’, ‘Round away from 0’ etc. We don’t need to worry about all these since GMAT uses only Round up i.e. 2.5 will be rounded up to 3.Let’s take a look at a question now which uses these fundamentals.Question: The exact cost price to make each unit of a widget is \$7.6xy7, where x and y represent single digits. What is the value of y?Statement 1: When the cost is rounded to the nearest cent, it becomes \$7.65.Statement 2: When the cost is rounded to the nearest tenth of a cent, it becomes \$7.65.Solution: The question is based on rounding. We need to figure out the value of y given some rounding scenarios. Let’s look at them one by one.Statement 1: When the cost is rounded to the nearest cent, it becomes \$7.65.When rounded to the nearest cent, the cost becomes 7 dollars and 65 cents. 6xy7 cents got rounded to 65 cents. When will .6xy7 get rounded to .65? When .6xy7 lies anywhere in the range .6457 to .6547. Note that in all these cases, when you round the number to 2 digits, it will become .65.Say price is 7.6468. We need to drop 68 but since 6 is ‘5 or greater’, 4 gets rounded up to 5.Similarly, say the price is 7.6543. We need to drop 43. Since 4 is ‘4 or smaller’, 5 stays as it is.So x and y can take various different values. This statement alone is not sufficient.Statement 2: When the cost is rounded to the nearest tenth of a cent, it becomes \$7.65Now the cost is rounded to the tenth of a cent which means 3 places after the decimal. But the cost is given to us as \$7.65. Since we need 3 places, the cost must be \$7.650 (which will be written as \$7.65)When will 7.6xy7 get rounded to 7.650? Now this is the tricky part of the question – from 7.6xy7, you need to drop the 7 and round up y. When you do that, you get 7.650. This means 7.6xy7 must have been 7.6497. Only in this case, when we drop the 7, we round up the 9 to make 10, carry the 1 over to 4 and make it 5. This is the only way to get 7.650 on rounding 7.6xy7 to the tenth of a cent. Hence x must be 4 and y must be 9. This statement alone is sufficient to answer the question.Answer (B)Hope you see that a few simple rules can make rounding questions quite easy.Karishma, a Computer Engineer with a keen interest in alternative Mathematical approaches, has mentored students in the continents of Asia, Europe and North America.

Rounding Up Some Official GMAT Questions!  [#permalink]

### Show Tags

09 Jun 2014, 12:00
 FROM Veritas Prep Admissions Blog: Rounding Up Some Official GMAT Questions! Last week we looked at some rounding rules. Today, let’s go over some official questions on rounding. They are quite simple and if we just keep the “Slip to the side and look for a 5” rule in mind, they can be easily solved.Question 1: If n = 2.0453 and n* is the decimal obtained by rounding n to the nearest hundredth, what is the value of n* – n?(A) -0.0053(B) -0.0003(C) 0.0007(D) 0.0047(E) 0.0153Solution: A quick note on place value nomenclature:Given a decimal 345.789, we know that 5 represents the units digit, 4 the tens digit and 3 the hundreds digit. Also, 7 represents the tenths digit, 8 the hundredths digit and 9 the thousandths digit and so on…Now let’s go back to this question:n = 2.0453We need to round n to the nearest hundredth which means we will retain 2 digits after the decimal. The third digit after the decimal is 5 so 2.0453 rounded to the nearest hundredth is 2.05.Thus n* – n = 2.05 – 2.0453 = 0.0047Answer (D)Question 2: If digit h is the hundredths digit in the decimal n = 0.2h6, what is the value of n, rounded to the nearest tenth?Statement 1: n < 1/4Statement 2: h < 5Solution: Given that n = 0.2h6We need to find the value of n rounded to the nearest tenth i.e. we need to keep only one digit after the decimal.Statement 1: n < 1/4In decimal form, it means n < 0.25If h were 5 or greater, n would become 0.256 or 0.266 or higher. All these values would be more than 0.25 so h must be less than 5 such as 0.246 or 0.236 etc. In all such cases, n would be rounded to 0.2This statement alone is sufficient.Statement 2: h < 5This is even simpler. Since we have been given that h is less than 5, when we round n to the tenths digit, we will get 0.2This statement alone is also sufficient.Answer (D)Question 3: If d denotes a decimal number, is d >= 0.5?Statement 1: When d is rounded to the nearest tenth, the result is 0.5.Statement 2: When d is rounded to the nearest integer, the result is 1.Solution: Again, a simple question!We need to find whether d is greater than or equal to 0.5 or not.Statement 1: When d is rounded to the nearest tenth, the result is 0.5.This means that whatever d is, when we round it to the nearest tenth, we get 0.5. What are the possible values of d? If d is anywhere from 0.450 to 0.5499999…, it will be rounded to 0.5Some of these numbers are less than 0.5 and others are greater than 0.5 so this statement alone is not sufficient.Statement 2: When d is rounded to the nearest integer, the result is 1.In this case d must be at least 0.5; only then can it be rounded to 1.d can be anything from 0.50 to 1.499999… In any case, d will be greater than or equal to 0.5.This statement alone is sufficient to answer the question.Answer (B)We hope you see that if we just remember the rules, we can solve most rounding questions very quickly and efficiently.Karishma, a Computer Engineer with a keen interest in alternative Mathematical approaches, has mentored students in the continents of Asia, Europe and North America.
