Reasoning: S = 160/6 * 18/5 = 96 kmph
Ans: (A)
Question: A 160 meter long train crosses a man standing on the platform in 6 sec. What is the speed of the train?
Options:
(A) 96 kmph
(B) 94 kmph
(C) 92 kmph
(D) 86 kmph
(E) 76 kmph

Rationale: In 8s the train crosses the pole and in 18 sec the train crosses one more stationary train
In 10 sec the train travels a distance of 400 mtrs
Speed = 400/10 = 40 m/s = 40 (3600/1000) = 40 * 18/5 = 144 kmph
The answer: (A)
Question: A Train requires 8 seconds to pass a pole while it requires 18 seconds to cross a stationary train which is 400 mtrs long. Find the speed of the train.
Options:
(A) 144 kmph
(B) 124 kmph
(C) 134 kmph
(D) 150 kmph
(E) 160 kmph

Reasoning: 1 man's 1 day work = 1/100
(10 men + 15 women)'s 1 day work = 1/8
15 women's 1 day work = (1/8 - 10/100) = 1/40
1 woman's 1 day work = 1/600
1 woman alone can complete the work in 600 days.
Ans: (E)
Question: 10 men and 15 women together can complete a work in 8 days. It takes 100 days for one man alone to complete the same work. How many days will be required for one woman alone to complete the same work?
Options:

(B) 667 days
(C) 177 days
(D) 187 days
(E) 600 days

(C) 300
(D) 179
(E) 172

Rationale: Largest 4 digit number is 9999

Hence largest 4 digit number exactly divisible by 98 = 9999 - 3 = 9996
The answer: (E)

Question: Calculate the largest 4 digit number which is exactly divisible by 98?
Options:
(A) 9800
(B) 9898
(C) 9702
