Reasoning: The integer should be divisible by: 10, 11, 12, 13, 14 and 15, that is 5*2, 11, 3*2^2, 13, 2*7, and 3*5. The least common multiple of these integers is the product of 13, 11, 7, 5, 3 and 2^2. Then, R/26 is (13 * 11 * 7 * 5 * 3 * 2^2)/2 * 13 = 11*7*5*3*2 = 2310.
Ans: (B)
Question: If J is the least positive integer that is divisible by every integer from 10 to 15 inclusive, then J/26 is =
Options:
(A)  1155
(B)  2310
(C)  4620
(D)  30030
(E)  60060
Rationale: Speed = 162*(5/18) m/sec = 45m/sec
Length of Train (Distance) = Speed * Time
45 * 12 = 540 meter
The answer: (A)
Question: A train running at the speed of 142 km/hr crosses a pole in 12 seconds. Find the length of the train.
Options:
(A) 540
(B) 288
(C) 200
(D) 340
(E) 712
Reasoning: Area of an equilateral triangle = √3/4 S2
If S = 12, Area of triangle = √3/4 * 12 * 12 = 36√3 cm2;
Ans: (D)
Question: What is the are of an equilateral triangle of side 12 cm?
Options:
(A) 64√5
(B) 64√9
(C) 64√4
(D) 36√3
(E) 64√2
Rationale: T = (100 * 16500)/(15 * 5000) = 22 years
The answer: (A)
Question: In how many years does a sum of Rs. 5000 yield a simple interest of Rs. 16500 at 15% p.a.?
Options:
(A) 22
(B) 20
(C) 25
(D) 30
(E) 35
Reasoning: (1056 / 26) gives remainder 16
10 + 16 = 26, So we need to add 10
Ans: (A)
Question: What is the least number should be added to 1056, so the sum of the number is completely divisible by 26?
Options:
(A) 10
(B) 20
(C) 30
(D) 40
(E) 50
Reasoning: Answer: Option C
