**1. The graph below shows the different commuting options chosen by commuters in the Farview City metropolitan region in 1995 and in 2005**.**The commuting mode whose ridership increased by approximately 29% from 1995 to 2005 is __________________. Option:**

1. bike

2. Subway & bus

3. commuter train

4. car**Ans:** commuter train**Explanation:** Well, we can estimate this one. A 29% increase is an increase of a little more than a quarter. Bikes tripled, so that’s way more than a quarter increase — that’s not correct.. The category “subway & bus” when from 3 to 5 million, more than a 50% — that’s not correct. Cars decreased, so that’s not correct. Even without looking at “commuter trains”, we can easily eliminate the other three. Notice “commuter trains” increased from 7 M to 9M, a 2M increase which is slightly more than one quarter of 7. That’s the answer, and we didn’t need the calculator.**2. The graph below shows the different commuting options chosen by commuters in the Farview City metropolitan region in 1995 and in 2005.**

Assume the graph above shows all commuters in the two relevant years. In 2005, the car commuters were _______ percent of all commuters.

Option:

a. 25

b. 32

c. 48

d. 60**Ans: 32Explanation: **In 2005, there were 8M car commuters, and 3 + 5 + 9 + 8 = 25M commuters total. That means, car users were 8/25. Multiply this fraction by 4/4 to get 32/100 = 32%.

If 100,000 participant start this process, and if all the percentages in the chart are correct, _______ people of them would win the entire competition.

Option:

a. 800

b. 3200

c. 7000

d. 10000

Option:

a. 16

b. 16.8

c. 20

d. 21.6

Folks who (1st = win, 2nd = place) = (0.40)*(0.40) = 0.16 = 16%

Folks who (1st = win, 2nd = win, 3rd = lose) = (0.40)*(0.20)*(0.70) = 0.056 = 5.6%

Add these: 16% + 5.6% = 21.6%**5. For years, the Bethel Company had Gamma division. The year 2008 was the first year that Rho division was in operation. The chart shows the profits generated by these two divisions. Assume these two divisions were the only source of profits for the Bethel Company during these years.**** In 2010 and 2011 combined, Rho division accounted for _____ % of Bethel’s profits.**Option:

a. 28.6

b. 42.4

c. 54.1

d. 73.2

From 2008 to 2011, Rho division increased by ______%

Option:

a. 80

b. 150

c. 200

d. 300**Ans**: 200**Explanation**: From 2008 to 2011, Rho increased from $7M to $21M, a three-fold increase. Be careful, though: when something triples, that’s NOT a 300% increase. No, it started at 100% ($7M), then increased by 100% (another $7M) and then another 100% (another $7M) — a 200% increase. Tripling is always a 200% increase.
