= Rs. 108.
Increase = 8%

Some articles were bought at 6 articles for Rs. 5 and sold at 5 articles for Rs. 6. Gain percent is ?

A. 30 %

B. 33 1/3 %

C. 35%

D. 44%

Answer : D. 44%

Explanation:

Suppose, number of articles bought = L.C.M. of 6 and 5 = 30

Cost Price (C.P) of 30 articles = Rs.( 5 / 6 ) x 30
= Rs. 25

Selling Price (S.P) of 30 articles = Rs.( 6 / 5 ) x 30
= Rs. 36

Gain % = ( 11 / 25 ) x 100%
= 44%

A dishonest dealer professes to sell his goods at Cost Price but still gets 20% profit by using a false weight. What weight does he substitute for a kilogram ?

A. 855 1/2 grams

B. 833 1/3 grams

C. 833 1/2 grams

D. 875 2/7 grams

Answer : B. 833 1/3 grams

Explanation:

Let the error is x gm. So we have
( error / True weight – error ) * 100 = %gain profit
= ( x / 1000 – x ) * 100 = 20
x / 1000 – x = 1 / 5
5x = 1000 – x
6x = 1000
x = 1000/6 gm

Hence the weight = 1000 – (1000 / 6)
833 1/3

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

Riya sold her car for 50000 less than what she bought it for and lost 8% at what price should she have sold her car, if she wanted to gain as much as she lost in the first transaction ?

A. 625000

B. 650000

C. 675000

D. 637000

E . 670000

Answer : C. 675000

Explanation :

Let Riya bought the car at Rs. x
so, cost price = x
Sold at Rs. 50000 less than Rs. x
so, selling price = x – 50000

Also, 50000 is 8% of x
50000 = 8/100 of x
50000 = 0.08x
or, x = 50000/0.08 = 625000

So, Riya bought at Rs. 625000.
To gain what she lost in her first transaction i.e., Rs 50000 she should have sold the car at Rs. 625000 + 50000
= Rs. 6,75,000

Revati brought a machine of 4,50,000 and sold it to raghu at profit. Raghu sold the machine to danush at loss of 10% for 4,95,000. What profit got ravi ?

A . 23 %

B . 21 %

C . 25 %

D . 22.22 %

Answer : D . 22.22 %

Explanation:

Raghu’s cost price (CP) is revati’s selling price (SP)
Raghu’s CP = (100/90) * 4,95,000 = 550000.
profit % = ( 100000 / 450000 ) * 100
= 22.22.
