Solutions:

1. In this type of transaction, there is always a loss
:. Loss per cent = (x2 / 100) = [(10×10) / 100]
= 1%

2. In Ist 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

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

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%

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

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

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)

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

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

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%
