ANSWERS - HURDLE 03 : PROFIT AND LOSS

Ans 1. Net Increase % = 12-6 –(12*6/100) = 6- 18/25 = 132/25 %
Let the original price = X
X*132/2500 +X= 2632
2632X/2500 = 2632
so X = 2500
Profit = 2632-2500 = 132.


Ans 2. Net reduction = 14 –25 – (14*25/100) = -11-7/2 = -14.5 %
So 14.5 % = 406
So 100 % = 2800
Price after increase of 14 % = 2800*114/100 = Rs. 3192

Ans 3. Let the decrease was by Y %
So we get 16 –Y – 16Y/100 = 1.5
16-116Y/100 = 1.5
-116Y/100 = -14.5
Y = 1450/116 = 12.5 %

Ans 4. Net Change = –10+7 –(10*7/100) = -3-7/10 = -37/10 %
Let the original price be X
X- 37X/1000 = 3852
963X/1000 = 3852
X= 4,000
Loss = 4000-3852= 148


Ans 5. Net Change = -12.5 + 8 –(12.5*8/100) = -5.5%
Let the price after 12.5% increase be Z
8 % of Z = 182
so Z= 2275
Let original price be X
X- 12.5X/100 = 2275
So X = 2600
Sale price = 2275 +182 = 2457
Loss = 2600-2457 = Rs 143


Ans 6. Out of a and b, a will lead to lesser increase so no need to calculate for b.
So for a it will be 24 % increase
For c ) it will be 30 –6 – (30*6/100) = 24 –1.8= 22.2 %
For d it will be –4+28 –(24*4/100) = 24 -.96 = 23.04 %
So with c we will have the minimum increase.

Ans 7 : Net Reduction = . –10-7 + 10*7/100 = -17 +.7 = -16.3%
Let the original price be X
16.3% of X = 978
so X = 6,000
First reduction = 10 % of 6,000 = 600
Second reduction = 978-600 = Rs. 378


Ans 8 . Initial price of the product = P*145/100 = 464
So P = 320
New price = 464 –160 = 304.
So percentage of decrease = 320*Q/100 = 304
Q = 95 , so decrease was by 5%
X + Y +XY/100 = 45
And X-Y –XY/100=- 5
Solving the two equations we get X = 20


Ans 9. Option 2. The passage define Bt cotton as a transgenic plant .
Read : " Bt cotton, a transgenic plant, produces an insect-controlling protein....... "

Transgenic means a plant or animal that contains genes from a different species. So option 2 is the best choice.

Ans 10 . Ans is Option 1.
Read : " The company responded quite wryly to the Minister's announcement......"
Wryly means expressing mixture of Irony and amusement.

Option 2 is not the right answer as the company never criticised the government, so their response cannot be termed as censorious.
