Q:

# A, B and C invest in the ratio of 3 : 4: 5. The percentage of return on their investments are in the ratio of  6 : 5 : 4. Find the total earnings, If B earns Rs. 250 more than A :

 A) Rs. 6000 B) Rs. 7250 C) Rs. 5000 D) None of these

Explanation:

A                  B                   C

investment                    3x                 4x                  5x

Rate of return              6y%              5y%                4y%

Return                           $\inline&space;\frac{18xy}{100}$             $\inline&space;\frac{20xy}{100}$             $\inline&space;\frac{20xy}{100}$

Total = (18+20+20) = $\inline&space;\frac{58xy}{100}$

B's earnings - A's earnings  = $\inline&space;\frac{2xy}{100}$ = 250

Total earning = $\inline&space;\frac{58xy}{100}$ = 7250

Q:

A women goes to market with Rs.500 to buy oranges.the prices of the oranges have decreased by 10% so he could buy 2kg more with the amount she had.What was the original price of the oranges ?

 A) 22.77 B) 25.77 C) 27.77 D) 29.77

Explanation:

If the price of the oranges decreases by 10%, the woman would save 10% of the money that is Rs.50 to buy the same amount as before.Now in Rs50 she can buy 2 kg more, therefore the current price of 1 kg of oranges is Rs25.Now this current price is after 10% reduction.

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

Q:

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%

Explanation:

Let the shopkeeper buy 300g for Rs.300. Now he sells 100g for Rs.110, another 100g for Rs120, and the rest 100g for Rs94.

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%

Q:

By selling an article at Rs.800, a shopkeeper makes a profit of 25%.At what price should he sell the article so as to make a loss of 25%?

 A) Rs.720 B) Rs.640 C) Rs.540 D) Rs.480

Explanation:

SP = Rs.800 ; Profit = 25%

$\inline \fn_cm CP = SP x \left [ \frac{100}{(100+P)} \right ]=800x\left [ \frac{100}{100+25} \right ]=Rs.640$

Now, CP = Rs.640

Loss = 25% = 25% of Rs.640 = Rs.160

Thus, SP = CP - Loss = Rs.640 - Rs.160 = Rs.480

Q:

A Shopkeeper sells two articles at Rs.1000 each, making a profit of 20% on the first article and a loss of 20% on the second article. Find the net Profit or loss that he makes?

 A) 4% B) 5% C) 6% D) 8%

Explanation:

SP of first article = Rs.1000

Profit = 20%

$\inline \fn_cm CP=SP\times [\frac{100}{(100+P)}]=Rs.\frac{2500}{3}$

SP of Second Article = Rs.1000

Loss = 20%

$\inline \fn_cm CP=SP\times [\frac{100}{(100-L)}]=Rs.1250$

So, Total SP = Rs.2000; Total CP = Rs.6250/3

As the CP is more than SP, he makes a loss.

Loss = CP - SP = (6250/3) - 2000 = Rs.(250/3)

So, Loss Percent = $\inline \fn_cm \left [ \frac{\frac{250}{3}}{\frac{6250}{3}} \right ]x100$= 4%
