__Solutions:__

**1.**In this type of transaction, there is always a loss

:. Loss per cent = (x

^{2}/ 100) = [(10×10) / 100]
= 1%

**Answer: a)**

**2.**In I

^{st}stock invested amount for the income of Rs.1 = Rs.(97/4)

In IInd stock, invested amount for the income
of Rs.1 = Rs.(107/5)

:. Ratio = (97/4):(107/5) = 485:428

So the first stock = [485 / (485 + 428)]

= Rs. 485

**Answer: d)**

**3.**Let original CP of sugar = Rs.x per kg

New CP of sugar = x × (90/100)

= Rs.(9x/10)

According to the given condition

(270/(9x/10)) – (270/x) = 1

=> [(2700 – 2430) / 9x ] = 1

=> (270/9x) = 1

=> x = (270/9)

= Rs.30 per kg

**Answer: b)**

**4.**Decrease in sale = 80% from 2008 to 2009

Now, sales of 2010 are same as in 2008

:. Increase in sales = [(100×a) / (100-a)]%

Here, a= 80% = [(100×80) / (100 – 80)]

= [(100×80)/ 20]=400%

**Answer: d)**

**5.**Since 1 h = 60 min or 3600 s and

1 min + 12 s = (60 + 12)s = 72 s

Then, y% of 3600 = 72

=> 3600 × (y/100) = 72

=> y = [(72×100)/3600]

=> y = 2

**Answer: a)**

**6.**Let the number be x.

Then, x-15 = 80% of x

=> x-15 =x×(80/100)

=> x-15=(4x/5)

=> 5x-75=4x

=> x=75

**Answer: a)**

**7.**Suppose, third number be 100.

Then, first number =130

Second number =140

So, 130=140×(x/100)

=> x=[(130×100)/140]

=> x=(650/7)

=> x=92(6/7)

**Answer: d)**

**8.**Suppose a got 100 marks, then B got 80 marks.

:. Per cent marks that A got more than B=
(20/80) ×100=25%

**Answer: b)**

**9.**Suppose, Tulsiram’s salary be Rs.x

Then, x×(4/100) = 720

=> x=[(100×720)/4] = Rs.18000

:.Kashyap’s salary = 18000×(100/120) =
Rs.15000

**Answer: a)**

**10.**Let maximum marks be x, then

Given, Ram got pass marks = 30% of x + 15 = x ×
(30/100)+ 15

Mohan got pass marks = x × (40/100) – 35

According to question.

=> 3x + 150 = 4x – 350

:. X=150+350=500

:. pass marks = 500 × (3/10) + 15 = 165

:.Necessary percentage for passing = (165/500)
× 100 = 33%
