question: A can do a certain work in 12 days. B is 60% more efficient than A. How many days does B alone take to do the same job ?
Options:
(A) 19
(B) 15
(C) 16
(D) 17
(E) 18
answer: Stream of consciousness: Ratio of time taken by A & B = 160:100 = 8:5 Suppose B alone takes x days to do the job. Then, 8:5::12:x = > 8x = 5*12 = > x = 15 days. The answer is (B).

q: In a division sum, the remainder is 5 and the divisor is 3 times the quotient and is obtained by adding 3 to the thrice of the remainder. The dividend is:
Options:
(A) 72
(B) 76
(C) 100
(D) 113
(E) 112
a: Stream of consciousness: Diver = (5*3)+3 = 18
3* Quotient = 18
Quotient = 6
Dividend = (Divisor * Quotient) + Remainder
Dividend = (18* 6) + 5 = 113 The answer is (D).

question: In how many different ways can the letters of the word 'EVER' be arranged?
Options:
(A) 12
(B) 280
(C) 300

(C) 3628812
(D) 3428800
(E) 3368800
answer: Stream of consciousness: Option 'B'
The total number of arrangements is
10P10 = 10! = 3628800 The answer is (B).
