Quants

Q1.The L.C.M of two numbers is 3 times of the largest number and the difference between the smallest number and H.C.F. of the two numbers is 12. Then find out the smallest number.

(a)12

(b)17

(c)15

(d)18

Sol: Let the two numbers be x and y(x>y)

L.C.M of both number = 3x

l.c.m * h.c.f=x*y

3x*h.c.f=x*y

y,  smallest number=3h.c.f

Also, y-h.c.f=12

3h.c.f-h.c.f=12

H.C.F=6

so, smallest number y= H.C.F +12

    =6+12

    =18

Q2. If 33% of the sum of two numbers is equal to 67% of difference of the same numbers and the sum of the same two numbers is equal to 469. Then find out the smaller number?

(a) 113

(b) 108

(c) 111

(d) 119

Sol :Let two numbers be A and B.

ATQ, 33% of (A+B) = 67% of (A-B)

34%A=100%B

AB=5017

Let A=50x and B=17x

ATQ,

50x+17x=469

x=7

Smaller number=17x=177 =119

Q3. How many seconds will a 500 metre long train take to cross a man walking with a speed of 3 km/hr in the direction of the moving train if the speed of the train is 63 km/hr?

  1. 25
  2. 30
  3. 40
  4. 45

Sol :  Speed of the train relative to man = 63-3 = 60 kmph

= 60 *(5/18)

= (50/3) 

Time to pass the man = 500 * (3/50) = 30 sec

Q4. Ravi and Kumar are working on an assignment. Ravi takes 6 hours to type 32 pages on a computer, while Kumar takes 5 hours to type 40 pages. How much time will they take, working together on two different computers to type an assignment of 110 pages?

  1. 7 hours and 30 minutes 
  2. 8 hours
  3. 8 hours 15 minutes
  4. 8 hours 25 minutes

Sol :     Number of pages typed by Ravi in 1 hour = 32/6 = 16/ 3

Number of pages typed by Kumar in 1 hour = 40/5 = 8

Number of pages typed by both in 1 hours = 16/3 + 8 = 40/3

Time taken by both to type 110 pages = 110 * (3/40) hours

= 8 hours 15 minutes

Q5. The sum of the squares of three numbers is 138, while the sum of their products taken two at a time is 131. Their sum is:

  1. 20
  2. 30
  3. 40
  4. 50

Sol : Let the numbers be a, b and c.

Then, a2 + b2 + c2 = 138 and (ab + bc + ca) = 131.

(a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca) = 138 + 2 x 131 = 400.

(a + b + c) = 400 = 20

Q1.If for a certain quantity of books, the publisher has to pay Rs. 30,600 as printing cost, then what will be the amount of royalty to be paid for these books?

  1. 19450
  2. 21200
  3. 22950
  4. 26150

Sol : Let the amount of Royalty to be paid for these books be Rs. r.

Then, 20 : 15 = 30600 : r         r = Rs. 30600 x 15 = Rs. 22,950.
      20

Q2. The price of the book is marked 20% above the C.P. If the marked price of the book is Rs. 180, then what is the cost of the paper used in a single copy of the book?

  1. 36
  2. 37.5
  3. 42
  4. 44.25

Sol : Clearly, marked price of the book = 120% of C.P.

Also, cost of paper = 25% of C.P

Let the cost of paper for a single book be Rs. n.

Then, 120 : 25 = 180 : n         n = Rs. 25 x 180 = Rs. 37.50 .
  120

Q3. If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?

  1. 187.50
  2. 191.50
  3. 175
  4. 180

Sol : For the publisher to earn a profit of 25%, S.P. = 125% of C.P.

Also Transportation Cost = 10% of C.P.

Let the S.P. of 5500 books be Rs. x.

Then, 10 : 125 = 82500 : x         x = Rs. 125 x 82500 = Rs. 1031250.
      10

S.P. of one book =  1031250 = Rs. 187.50 .
5500
