A watch was sold at a loss of 10%. If it was sold for Rs.140 more, there would have been a gain of 4%. What is the cost price ?

A. Rs 1000

B. Rs 1140

C. Rs 860

D. Rs 760

Answer : A. Rs 1000

Explanation:

Let the cost price of the watch be x.
It was sold for 10% loss that is 90x/100

If it was sold for 140 more, the price would be 90x/100 + 140 and this would be 4% gain which is 104x/100

So, 104x/100 = 90x/100 + 140
Multiply through by 100, we have
104x =90x + 14000
Subtract 90x from both sides, we have
14x = 14000
Divide both sides by 14, we have
x = 1000
So, the cost price is 1000

A sells a camera to B at profit of 20% and B sells it to C at a profit of 25%. If C pays Rs 450, what price did A pay for the camera ?

A . Rs 300

B . Rs 350

C . Rs 400

D . Rs 450

Answer : A . Rs 300

Explanation:

Let cost price for A = Rs. 100.
SP for A = CP for B = 100 + 20% of 100 = 120.
SP for B = CP for C = 120 + 25% of 120 = 150.

Given,
CP for C = 450
So,
150 = 450
1 = 450/150
100 = (450 *100)/150 = Rs. 300.
CP for A = Rs. 300.

On selling an article for Rs 1020, a merchant loses 15%. For how much price should he sell the article to gain 12% on it ?

A . Rs 1344

B . RS 1400

C . Rs 1200

D . RS 1500

Answer : A . Rs 1344

Explanation:

Selling Price (S.P) = Rs 1050
Loss = 15%
Let Cost Price (C.P) = 100%
SP = CP – Loss% = 100% – 15% = 85%

85% = Rs 1020
Therefore Cost Price = 100% = 1020/85 x 100 = 1200

To get 12% gain => SP = CP + Profit %
= 100 % + 12 %
= 112 %
= 1200 / 100 x 112 = Rs 1344
