Options:
(A) 23
(B) 78
(C) 27
(D) 29
(E) 20
answer: Stream of consciousness: Let the distance covered by the taxi be 'x' km. Then, distance covered by bus = (60 – x) km. 20x + 10 (60 – x)⇒20x + 600 – 10x = 800 10x = 200 ⇒ x = 20 km. He traveled 20 km by taxi. The answer is (E).

(E) 253
a: Stream of consciousness: 400*(90/100)* (95/100) = 342 The answer is (C).


question: The speed of a train is 90 kmph. What is the distance covered by it in 10 minutes?
Options:
(A) 15
(B) 66
(C) 77

q: If the ratio of boys to girls in a class is B and the ratio of girls to boys is G; then 7 (B + G) is ?
Options:
(A) more than 7
(B) Less than 3
(C) More than 3
(D) Less than 1/3
(E) none of these
a: Stream of consciousness: Let number of boys = x
Let number of girls = y
Therefore x/y = B and y/x = G
7(B + G) = 7[(x/y) + (y/x)] = 7[(x2 + y2)/xy] > 7 The answer is (A).


question: In an office, 20 percent of the workers have at least 5 years of service, and a total of 16 workers have at least 10 years of service. If 90 percent of the workers have fewer than 10 years of service, how many of the workers have at least 5 but fewer than 10 years of service?
Options:
(A)  32
(B)  64
(C)  50
(D)  144
(E)  160
answer: Stream of consciousness: (10/100)Workers = 16 = > number of workers = 160
(20/100)*Workers = x+16 = > x = 32 The answer is (A).


question: What amount does Kiran get if he invests Rs. 16000 at 15% p.a. simple interest for four years?
Options:
(A) 29893
(B) 27773
