Directions: Read the following questions carefully and choose the right answer.
Important for :
1
The average of 12 numbers is 14. If four numbers 7, 8, 13, and 14 are replaced by 3 numbers having average of 12. What is the difference between the averages of initial numbers and final numbers?
» Explain it
D
Since the avg of 12 numbers is 14, the total becomes 12 × 14= 168

From this total, 4 numbers are subtracted: 168 – (7 + 8 + 13 + 14) = 126

In this number, three numbers of average 12 is added

126 + (3 × 12) = 162

This number is divided by 11 because now there are 11 numbers instead of 12

162 / 11 = 14.72

The difference between the initial and final avg is 14.72 – 14 = 0.72

Hence, option D is correct.
2
In the village of Rampur, the percentage of female population in the total population is 55%. The number of people who possess sheep as cattle is 44. Out of the sheep owners, 3/4th are female. If out of the total female population, only 25% women own sheep. What is the total population of Rampur?
» Explain it
D
In this type of question, attention should be given to the language of the question.

Since total number of sheep are 44 and of those 3/4th are female, it means 33 women own sheep.

It is given that of all the women, only 25% (or one fourth) own sheep. It means, total number of women are:

33 x 4 = 132

It is also given that the percentage of female population is 55% of the total population in the village.

So,, by the rule of proportion

55% ≡ 132 

100% ≡ ?

Therefore, ? = 240

Option D is hence the correct answer.
3
Mukund buys 5 watches at the rate of Rs. 5000 each. He then sells them separately at the profit of 10%, 20%, 30%, 40% and 50%. He then buys an expensive watch investing the profit he earned by selling watches, marks it up 50% and offer discounts of 20%. What is the total profit earned by Mukund?
» Explain it
D
The average profit on the watches is 30% (because the given profit% are in AP and there the middle term has to be the average.)

So the profit made on one watch is 30% of 5000 = 1500

Total profit = 1500 × 5 = 7500

This is the cost price of the expensive watch which is sold at

⇒ 80% (after discount) × 150% (after including profit) of 7500 

⇒ 9000

Since the only cost incurred was the cost for 5 watches and after that only the profit has been reinvested. So the total profit earned is Rs. 9000.

Option D is hence the correct answer.
4
A sum of Rs. 9960 was borrowed at 15/2% per annum compound interest and paid back in two years in two equal annual installments. What was the amount of each installment?
» Explain it
B
Let the each instalment be x.

x  +    x      = 9960
( 1 +  15 ) ( 1 +  15 ) 2
2 × 100   2 × 100    

x  +    x      = 9960
( 1 +  3 ) ( 1 +  3 ) 2
40   40    

⇒   40 x  +  1600 x  = 9960
43 1849

⇒   1720 x + 1600 x  = 9960
1849
⇒  3320 x = 9960 × 1849 ⇒  x = Rs. 5547

Hence, option B is correct.
5
A card is drawn from a perfectly shuffled deck of cards. What is the probability that the card drawn is a spade and is an even numbered card?
» Explain it
E
There are 52 cards in a deck and there are four suits of cards - Spade, Club, Heart and Diamond.

So, probability of getting a card of Spade

13  =  1
52 4
 


Each of these cards contain an ace, 3 face cards and 9 numbered cards. The numbers are 2, 3, 4, 5, 6, 7, 8, 9 and 10.

So, there are total 13 cards of spade and of that only 5 are even numbered ones. Therefore, we can say that total number of cards that are spade and are even numbered are 5.

Probability of the card being even numbered out of all cards of Spade

5
13
 


Therefore, probability of a card being one from Spade and an even numbered one
 

1  ×  5  =  5
4 13 52

Hence, option E is correct.
