A, B, C and D play a game of cards. A says to B. "If I give you 8 cards, you will have as many as C has and I shall have 3 less than what C has. Also if I take 8 cards from C, I shall have twice as many as D has." If B and D together have 50 cards, how many cards have A got?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 3

If we read given question carefully, we get,
B+8 = C ---(i)
A-8 = C-3 ---(ii)
A+6 = 2D ---(iii)
B+D = 50 ---(iv)

Putting C = A -5 from (ii) into (i), we have :
B+8 = A-5 or A-B = 13 ---(v)

Putting D = 50-B from (iv) and (iii), we have :

A+6 = 100-2B or A+2B = 94 ---(vi)

Solving (v) and (vi), we get 
B = 27 and A = 40

Test: Arithmetic Reasoning- 3 - Question 9

In a family, a couple has a son and a daughter. The age of the father is three times that of his daughter and the age of the son is half of that of his mother. The wife is 9 years younger to her husband and the brother is seven years older than his sister. What is the age of the mother ?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 9

Let the daughter's age be x years.

Then, father's age = (3x) years.

Mother's age = (3x - 9) years; Son's age = (x + 7) years.

So, x + 7 = (3x-9)/2 2x + 14 = 3x - 9 x = 23.

Therefore Mother's age = (3X - 9) = (69 - 9) years = 60 years.

Mr. X, a mathematician, defines a number as 'connected with 6 if it is divisible by 6 or if the sum of its digits is 6, or if 6 is one of the digits of the number. Other numbers are all 'not connected with 6'. As per this definition, the number of integers from 1 to 60 (both inclusive) which are not connected with 6 is

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 11

Numbers from 1 to 60, which are divisible by 6 are : 6,12,18, 24, 30, 36,42, 48, 54, 60.

There are 10 such numbers.

Numbers from 1 to 60, the sum of whose digits is 6 are : 6, 15, 24, 33, 42, 51, 60.

There are 7 such numbers of which 4 are common to the above ones. So, there are 3such uncommon numbers.

Numbers from 1 to 60, which have 6 as one of the digits are 6, 16, 26, 36, 46, 56, 60.

Clearly, there are 4 such uncommon numbers.

So, numbers 'not connected with 6' = 60 - (10 + 3 + 4) = 43.

So, total weight of the cake = [2 x (20 x6)]g= 240 g.

Test: Arithmetic Reasoning- 3 - Question 15

A total of 324 coins of 20 paise and 25 paise make a sum of Rs. 71. The number of 25-paise coins is

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 15

Let the number of 20-paise coins be x. Then, number of 25-paise coins = (324 - x).

Therefore 0.20 x x + 0.25 (324 - x) = 71 20x + 25 (324 - x) = 7100

5x= 1000 x = 200. Hence, number of 25-paise coins = (324 - x) - 124.

Test: Arithmetic Reasoning- 3 - Question 16

A player holds 13 cards of four suits, of which seven are black and six are red. There are twice as many diamonds as spades and twice as many hearts as diamonds. How many clubs does he hold ?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 16

Clearly, the black cards are either clubs or spades while the red cards are either diamonds or hearts.

Let the number of spades be x. Then, number of clubs = (7 - x).

Number of diamonds = 2 x number of spades = 2x;

Number of hearts = 2 x number of diamonds = 4x.

Total number of cards = x + 2x + 4x + 7 - x = 6x + 7.

Therefore 6x + 7 = 13 6x = 6 x - 1.

Hence, number of clubs = (7 - x) = 6.

Test: Arithmetic Reasoning- 3 - Question 17

The taxi charges in a city comprise of a fixed charge, together with the charge of the distance covered. For a journey of 16 km, the charges paid are Rs. 156 and for a journey of 24 km, the charges paid are Rs. 204. What will a person have to pay for travelling a distance of 30 km?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 17

Let the fixed charge be Rs. x and variable charge be Rs.y per km. Then,

x + 16y = 156 ...(i) and

x + 24y = 204 ...(ii)

Solving (i) and (ii), we get: x = 60, y = 6.

Therefore Cost of travelling 30 km = 60 + 30 y = Rs. (60 + 30 x 6) = Rs. 240.

Test: Arithmetic Reasoning- 3 - Question 18

Test: Arithmetic Reasoning- 3 - Question 19

At the end of a business conference the ten people present all shake hands with each other once. How many handshakes will there be altogether ?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 19

Clearly, total number of handshakes = (9+ 8 + 7 + 6 + 5 + 4 + 3 + 2+1) = 45.

Test: Arithmetic Reasoning- 3 - Question 20

After distributing the sweets equally among 25 children, 8 sweets remain. Had the number of children been 28, 22 sweets would have been left after equal distribution. What was the total number of sweets ?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 20

Let the total number of sweets be (25x + 8).

Then, (25x + 8) - 22 is divisible by 28

(25x - 14) is divisible by 28 28x - (3x + 14) is divisible by 28

(3x + 14) is divisible by 28 x = 14.

Therefore Total number of sweets = (25 x 14 + 8) = 358.

Test: Arithmetic Reasoning- 3 - Question 21

A group of 1200 persons consisting of captains and soldiers is travelling in a train. For every 15 soldiers there is one captain. The number of captains in the group is

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 21

Clearly, out of every 16 persons, there is one captain. So, number of captains (1200/16) = 75.

Test: Arithmetic Reasoning- 3 - Question 22

In a caravan, in addition to 50 hens, there are 45 goats and 8 camels with some keepers. If the total number of feet be 224 more than the number of heads in the caravan, the number of keepers is

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 22

Let number of keepers be x. Then,

Total number of feet = 2 x 50 + 4 x 45 + 4 x 8 + 2x = 2x + 312.

Total number of heads = 50 + 45 + 8 + x= 103 + x.

Therefore (2x + 312) = (103 + x) + 224 or x = 15.

Test: Arithmetic Reasoning- 3 - Question 23

A monkey climbs 30 feet at the beginning of each hour and rests for a while when he slips back 20 feet before he again starts climbing in the beginning of the next hour. If he begins his ascent at 8.00 a.m., at what time will he first touch a flag at 120 feet from the ground?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 23

Net ascent of the monkey in 1 hour = (30 - 20) feet = 10 feet.

So, the monkey ascends 90 feet in 9 hours i.e. till 5 p.m.

Clearly, in the next 1 hour i.e. till 6 p.m. the monkey ascends remaining 30 feet to touch the flag.

Test: Arithmetic Reasoning- 3 - Question 24

A number consists of two digits whose sum is 11. If 27 is added to the number, then the digits change their places. What is the number ?

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 24

Let the ten's digit be x. Then, unit's digit = (11 - x).

So, number = 10x + (11 - x) = 9x + 11.

Therefore (9x + 11) + 27 = 10 (11 - x) + x 9x + 38 = 110 - 9x 18x = 72 x = 4.

Thus, ten's digit = 4 and unit's digit = 7.

Hence, required number = 47.

Test: Arithmetic Reasoning- 3 - Question 25

An enterprising businessman earns an income of Re. 1 on the first day of his business. On every subsequent day, he earns an income which is just double of that made on the previous day. One the 10th day of business, his income is

Detailed Solution for Test: Arithmetic Reasoning- 3 - Question 25

Income on the first day = Re. 1.

Income on the 2nd day = Rs. (1x2) = Rs. 21.

Income on the 3rd day = Rs. (21 x 2) = Rs. 22 and so on. Thus, Income on the rath day = Rs. 2n-1.

Therefore Income on the 10th day = Rs. 29.
