Question 1

#### What is the sum ( in RS) which when divided among X Y Z in the proportion 3:5:7 provides rupees 8000 more to Z then what it would have done to him when the proportion is 11 : 15 : 19?

#### 180000

#### 120000

#### 175000

#### 135000

Answer

#### Option= 180000

#### X:Y:Z

#### 3: 5: 7

#### Z got 8000 more = 2 parts more than Y

#### If 2 parts = 8000

#### Then 1 part = 4000

#### Final ratio = 11: 15: 19 = 45 parts

#### 45 x 4000 = Rs 180000

Question 2

#### A man has to travel 50 km in 2 hours. He could cover 20 km in one hour, and then had to stop for 10 minutes for refueling. By What factor should he increase his speed with reference to that during the first hour so as to be able to complete the journey as per schedule?

Question 4

#### X is four times as efficient as Y in respect of doing a particular work. Working together they complete the work in 16 days. In how many days y working alone will be able to half the work?

#### Â

#### 80

#### 20

#### 40

#### 60

Answer

#### Option = 40

#### Efficiency of X = 4a

#### Efficiency of Y = a

#### Time taken by both to complete a work = 16 days

#### Â

#### Â

#### a = 20

#### Hence X will do the work in 20 days

#### And Y will do the work in 80 days

#### Thus Y will do half of work in 40 days

Question 5

#### IfÂ Â = 225 x 405, find the value ofÂ

#### Â

#### 27

#### 81

#### 125

#### 25

Answer

#### Option = 27

#### Prime Factorization of 225 = 5 x 5 x 3 x 3

#### Prime Factorization of 405 = 3 x 3 x 3 x 3 x 5

#### 5336Â =Â 5X3Y

#### So X = 3 and Y = 6

Now, X2y – 3xÂ = Â 32(6) – 3(3)

#### 312 – 9Â = 33Â = 27

Question 6

#### The collection of numbers which comprise the data given below is arranged in ascending order.

Question 8

#### After purchasing two copies of the same book, X sold them respectively at 0.8 and 1.4 times their cost prices. What was the percentage gain earned or loss incurred by X?

#### 10% loss

#### 5% gain

#### 10% gain

#### 5% loss

Answer

#### Option = 10% gain

#### Let the C.P of each copy be Rs 100

#### ATQ one copy is sold at 0.8 x 100 = 80

#### Â Â Â Â One copy is sold at 1.4 x 100 = 140

#### Total money spent in buying the copies = Rs 200

#### Total money earned after selling the copies = Rs (80 + 140) = Rs 220

#### Total gain of Rs 20. Therefore gain% = 10%.
