Deloitte Profits and Loss Questions and Answers Quiz-1

Let the cost price be 100%. It is sold at 10% loss. So it is sold at
90% of the cost price.
90 % of the cost price + 450 = 108% of the Cost price
=> 18% of the cost price = Rs 450

Cost price of the book =\frac{450}{18}\times 100

= Rs 2500

Here pofit is the twice the loss
Profit = 2 Loss
SP –CP = 2 (CP – SP)
480 –CP = 2(CP – 300)
3 CP = 1080
CP= 360

Selling price=1020

loss=15%

S.P=100%-15%=85%

85%=Rs.1020

C.P=100%=\frac{1020}{85}\times100=1200

gain%=>S.P=C.P+Profit%

100%+12%=112%

\frac{1200}{100}\times 112

=Rs 1344

SP(A) = \frac{120}{100}\times CP(A)

SP(A) = CP(B)
SP(B) = \frac{125}{100}\times CP(B) =\frac{125}{100}\times SP(A) =\frac{125}{100}\times \frac{120}{100}\times CP(A) --- 1
SP(B) = CP(C) = 450 -- 2
Solve 1 and 2
we get
450 =\frac {125}{100}\times \frac{120}{100}\times CP(A)
CP(A) = 300

CP = a

SP = a \times \frac{90}{100} = \frac{9a}{10}

SP should be = \frac{9a}{10} + 140

a \times \frac{104}{100} =\frac{ (9\times a + 1400)}{10}

104a = 90a + 14000

14a = 14000

a = 1000

CP = Rs.1000

Let the original price be 100

His purchase price 80

His selling price 80\times\frac{140}{ 100} = 112

This gives 12 percent profit on the original price

If the cost price is Rs.100, then to get a profit of 20%, the selling price
should be Rs.120.
If 120kg is to be sold, and the dealer gives only 100kg, to get a profit of 20%.
How many grams he has to give instead of one kilogram(1000 gm).
120 gm ------ 100 gm
1000 gm ------ ?
1000\times\frac{ 100}{120}

= \frac{2500}{3}

= 833\frac{ 1}{3} grams.

15 CP = 18 SP

18 --- 3 CP loss

100 --- ?

\frac{3}{18}\times 100

= 16\frac{ 2}{3} .% loss

Let C.P of one article be Rs x
C.P of 13 article = Rs 13x
S.P of 11 article= Rs 13x
C.P of 11 articles = Rs 11x
Gain= 13x-11x=Rs 2x
Gain percent = \frac{2x}{11x}\times 100

=18.18%

=18\frac{2}{11}

\frac{20}{(100-20)}=25%
25% is equivalent to 10 kg
10 x 4=40
\frac{100}{40}=2.5
the original price is 2.5 kg
