Q:

# A person sold two cows each for Rs.9900. If he gained 10% on one and lost 20% on the other, then which of the following is true?

 A) He Gained Rs. 200 B) He lost Rs. 200 C) He neither gained nor lost D) None of the above

Answer:   D) None of the above

Explanation:

The CP of profitable cow  = $\inline&space;\frac{9900}{1.1}=9000$

and profit = Rs. 900

The  CP of loss yielding cow = $\inline&space;\frac{9900}{0.8}=12375$

and loss = Rs. 2475

so, the net loss = 2475 - 900 = 1575

Q:

If the cost price of a certain object doubles, then the loss gets tripled of what it was initially. The initial loss % was ?

 A) 0 % B) 25 % C) 75 % D) 50 %

Explanation:

Let the cost price be x and selling price be y.
Loss = x – y

When the cost price doubles, the loss gets tripled.
So it becomes like this, 2x – y = 3(x-y)

$\inline \fn_jvn \small \Rightarrow x=2y$

Loss % = $\inline \fn_jvn \small \left ( \frac{loss}{c.p} \right )\times 100$ = $\inline \fn_jvn \small \left ( \frac{2y-y}{2y} \right )\times 100$ = 50 %

Q:

The profit earned by selling an article for Rs.753 is equal to the loss incurred when the same article is sold for Rs.455.What should be the sale price for making 50% profit ?

 A) Rs.855 B) Rs.955 C) Rs.906 D) Rs.896

Explanation:

Let C.P =Rs. x

Then as given, (753 - x ) = (x - 455) $\inline \fn_jvn \Rightarrow$ 2x = 1208 $\inline \fn_jvn \Rightarrow$ x = 604

There fore S.P= 150% of 604 => Rs. $\inline \fn_jvn \frac{150}{100}\times 604$ = Rs.906

Therefore, the original price = $\inline \frac{25}{0.9}=Rs\, 27.77$

A shopkeeper sells one-third of his goods at a profit of 10%, another one-third at a profit of 20%, and the rest at a loss of 6%.What is his overall profit percentage ?

 A) 6% B) 8% C) 10% D) 12%

Therefore, the total amount he receives = Rs.110 + Rs.120 + Rs.94 = 324.

Therefore, the shopkeeper spends Rs.300 and gets back Rs.324.

Therefore, his profit percentage = $\inline \frac{24}{300}\times 100$ % = 8%
