My answer is A but looks like the answer choice is E. Can you please explain. The first question does provide the ratio and the total of the buses in the garage with which we can solve the equation.

(1)

One Possibility:

4x + 6x + 7x + 26 = 298

=> 17x = 272

=> x = 16

So # of green buses = s = 16 * 7 = 112

Other possibility - q = 4, r = 6, s = 7

So s can be 7 as well
InSufficient

(2)

q gives us only the number of buses in blue zone, but no information about buses in grren zone

Insufficient

(1) + (2)

q = 64, then r = 6/4 * 64 = 96, and s = 7/4 * 64 = 112

Total = 64 + 96 + 112 + 26 = 298

Sufficient

Answer - C

Are you sure the OA is E ?

(1) The ratio of q to r to s is 4:6:7 and 26 buses are in garages.

(2) q = 64


1) This is clearly no A because we did not have proportion of the bases in guarage to other. Insuff
2) q=64 / we have no relationtion with other type

1) + 2)
Give as q/s=4/7, from here 64/s=4/7. s = 64*7/4=16*7=112

my answer is C.

I dont understand wy the correct answer is E

Please explain somebody

Could you please help me to understand this a little better?

Form statement A, I am not finding the second possibility suggested by subhash

There are 26 busses in the garage, so at the time of division, there are only 298-26 bussed available to be divided among the 3 regions

so x= 16. With that we can arrive at the solution? whats the catch here?

Answer should be "A" unless Kaplan goes like: hehe.. tricked ya!!! I didn't tell you that buses can also be in the depots and bus stations; in which case, it should be "E". :)

Should be A, ratio 4:6:7 cant be reduced.

298-26= 272
272/17= 16
16*7= 112

Should be A .

Question clearly states that q + r + s + t = 298.

Not sure why it is E :S
