Test: Quantitative Reasoning- 1 - Question 2

Two bus tickets from city A to B and three tickets from city A to C cost Rs. 77 but three tickets from city A to B and two tickets from city A to C cost Rs. 73. What are the fares for cities B and C from A ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 2

Let Rs. x be the fare of city B from city A and Rs. y be the fare of city C from city A.

Then, 2x + 3y = 77 ...(i) and

3x + 2y = 73 ...(ii)

Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y = 17.

Putting y = 17 in (i), we get: x = 13.

Answer cannot be determined until we have the "Ratio of girls to boys"
 

Test: Quantitative Reasoning- 1 - Question 5

A, B, C, D and E play a game of cards. A says to B, "If you give me three cards, you will have as many as E has and if I give you three cards, you will have as many as D has." A and B together have 10 cards more than what D and E together have. If B has two cards more than what C has and the total number of cards be 133, how many cards does B have ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 5

Clearly, we have :

B-3 = E ...(i)

B + 3 = D ...(ii)

A+B = D + E+10 ...(iii)

B = C + 2 ...(iv)

A+B + C + D + E= 133 ...(v)

From (i) and (ii), we have : 2 B = D + E ...(vi)

From (iii) and (vi), we have : A = B + 10 ...(vii)

Using (iv), (vi) and (vii) in (v), we get:

(B + 10) + B + (B - 2) + 2B = 133 5B = 125 B = 25.

Test: Quantitative Reasoning- 1 - Question 6

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 6

Test: Quantitative Reasoning- 1 - Question 7

A woman says, "If you reverse my own age, the figures represent my husband's age. He is, of course, senior to me and the difference between our ages is one-eleventh of their sum." The woman's age is

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 7

Let x and y be the ten's and unit's digits respectively of the numeral denoting the woman's age.
Then, woman's age = (10x + y) years; husband's age = (10y + x) years.

Therefore (10y + x)- (10X + y) = (1/11) (10y + x + 10x + y)
⇒ (9y-9x) = (1/11)(11y + 11x) = (x + y)
⇒ 10x = 8y x = (4/5)y

Clearly, y should be a single-digit multiple of 5, which is 5.
So, x = 4, y = 5.
Hence, woman's age = 10x + y = 45 years.

Test: Quantitative Reasoning- 1 - Question 8

A girl counted in the following way on the fingers of her left hand : She started by calling the thumb 1, the index finger 2, middle finger 3, ring finger 4, little finger 5 and then reversed direction calling the ring finger 6, middle finger 7 and so on. She counted upto 1994. She ended counting on which finger ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 8

Clearly, while counting, the numbers associated to the thumb will be : 1, 9,17, 25,.....

i.e. numbers of the form (8n + 1).

Since 1994 = 249 x 8 + 2, so 1993 shall correspond to the thumb and 1994 to the index finger.

Test: Quantitative Reasoning- 1 - Question 9

A man has Rs. 480 in the denominations of one-rupee notes, five-rupee notes and ten-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 9

Let number of notes of each denomination be x.

Then x + 5x + 10x = 480

⇒ 16x = 480

∴ x = 30.
total number of notes is = x + x + x .

Hence, total number of notes = 3x = 90.

Test: Quantitative Reasoning- 1 - Question 10

What is the product of all the numbers in the dial of a telephone ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 10

Since one of the numbers on the dial of a telephone is zero, so the product of all the numbers on it is 0.

Test: Quantitative Reasoning- 1 - Question 11

A is 3 years older to B and 3 years younger to C, while B and D are twins. How many years older is C to D?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 11

Since B and D are twins, so B = D.
Now, A = B + 3 and A = C - 3.
Thus, B + 3 = C - 3
⇒ D + 3 = C-3
⇒ C - D = 6

In a garden, there are 10 rows and 12 columns of mango trees. The distance between the two trees is 2 metres and a distance of one metre is left from all sides of the boundary of the garden. The length of the garden is

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 13

Each row contains 12 plants.

There are 11 gapes between the two corner trees (11 x 2) metres and 1 metre on each side is left.

Therefore Length = (22 + 2) m = 24 m.

Test: Quantitative Reasoning- 1 - Question 14

12 year old Manick is three times as old as his brother Rahul. How old will Manick be when he is twice as old as Rahul ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 14

Manick's present age = 12 years, Rahul's present age = 4 years.

Let Manick be twice as old as Rahul after x years from now.
Then, 12 + x = 2 (4 + x)
⇒ 12 + x = 8 + 2x
⇒ x = 4.

Hence, Manick's required age = 12 + x = 16 years.

Test: Quantitative Reasoning- 1 - Question 15

A tailor had a number of shirt pieces to cut from a roll of fabric. He cut each roll of equal length into 10 pieces. He cut at the rate of 45 cuts a minute. How many rolls would be cut in 24 minutes ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 15

Number of cuts made to cut a roll into 10 pieces = 9.

Therefore Required number of rolls = (45 x 24)/9 = 120.

Test: Quantitative Reasoning- 1 - Question 16

In a class of 60 students, the number of boys and girls participating in the annual sports is in the ratio 3 : 2 respectively. The number of girls not participating in the sports is 5 more than the number of boys not participating in the sports. If the number of boys participating in the sports is 15, then how many girls are there in the class ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 16

Let the number of boys and girls participating in sports be 3x and 2x respectively.
Then, 3x = 15 or x = 5
⇒ Number of girls participating in sports = 2x = 10
⇒  Number of students not participating in sports = 60 - (15 + 10) = 35

Let number of boys not participating in sports be y.
Then, number of girls not participating in sports = (35 -y)

Therefore (35 - y) = y + 5
⇒  2y = 30
⇒  y = 15

So, number of girls not participating in sports = (35 - 15) = 20

Hence, total number of girls in the class = (10 + 20) = 30

Test: Quantitative Reasoning- 1 - Question 17

There are deer and peacocks in a zoo. By counting heads they are 80. The number of their legs is 200. How many peacocks are there ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 17

Let x and y be the number of deer and peacocks in the zoo respectively. Then,

x + y = 80 ...(i) and

4x + 2y = 200 or 2x + y = 100 ...(ii)

Solving (i) and (ii), we get) x = 20, y = 60.

Test: Quantitative Reasoning- 1 - Question 18

A man wears socks of two colours - Black and brown. He has altogether 20 black socks and 20 brown socks in a drawer. Supposing he has to take out the socks in the dark, how many must he take out to be sure that he has a matching pair ?

Total number of routes from Bristol to Carlisle = (4 x 3 x 2) = 24.

Test: Quantitative Reasoning- 1 - Question 20

Mac has £ 3 more than Ken, but then Ken wins on the horses and trebles his money so that he now has £ 2 more than the original amount of money that the two boys had between them. How much money did Mac and Ken have between them before Ken's win?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 20

Let money with Ken = x. Then, money with Mac = x + £ 3.

Now, 3x = (x + x + £ 3) + £ 2 ⇒ x = £ 5.

Therefore Total money with Mac and Ken = 2x + £ 3 = £ 13.

Test: Quantitative Reasoning- 1 - Question 21

In a class, there are 18 boys who are over 160 cm tall. If these constitute three-fourths of the boys and the total number of boys is two-thirds of the total number of students in the class, what is the number of girls in the class ?

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 21

Let the number of boys be x. Then, (3/4)x = 18 or x = 18 x(4/3) = 24.

If total number of students is y, then (2/3) y = 24 or y = 24 x (3/2) = 36.

Therefore Number of girls in the class = (36 - 24) = 12.

Test: Quantitative Reasoning- 1 - Question 22

A father is now three times as old as his son. Five years back, he was four times as old as his son. The age of the son (in years) is

Detailed Solution for Test: Quantitative Reasoning- 1 - Question 22

Let son's age be x years. Then, father's age = (3x) years.
Five years ago, father's age = (3x - 5) years and son's age = (x - 5) years.

So, 3x - 5 = 4 (x - 5)
⇒ 3x - 5 = 4x - 20
⇒  x = 15
