A train travels at an average speed of 20 mph through urban areas, 50 mph
through suburban areas, and 75 mph through rural areas. If a trip consists of
traveling half an hour through urban areas, 3-1/2 hours through suburban areas,
and 3 hours through rural areas, what is the train’s average speed for the entire
trip?
a. 50 mph
b. 53-2/7 mph
c. 54-3/7 mph
d. 58-4/7 mph
e. 59-2/7 mph

can any one tell how to solve it?

Very easy..
Use weighted average method

20(0.5)+ 50(3.5)+75(3) = 410

sum of all the weights = 0.5+3.5+3 = 7

now divide 410 by sum of all weights = 410/7 = 58-4/7

Answer = Option..D= 58-4/7

mathematics portion are quantitative or analytical and bank officer guide by dogars is enough for preparation of test?kindly suggest me one book which is sufficent for preparation. I Shall be very thankful

Get any GMAT latest edition available in market.. as dogars will not cover complete section.. dogar is good for other sections i guess..

Combined Preparation from GMAT, Dogar, Economics books will be enough

it would be better to get prepared from dogar it has got everything and in Gmat most of the topics are missing

what about NTS NAT2 book?.......it has everything in it.
