answer :- 
 
the cost of this is:- 
 
total percentage is = 100%. 
but loss is = 10% 
so (100-10)% = 90%. 
the cot sold is =Rs. 80 
then 
= ( 90*80) / 100 
=Rs.72

Let X be the original price of the product. 
If the product is sold at Rs. 80 less then original price, he would suffer 10% loss. 
So it will be  
(x-80) = x-10x/100 
or, 
x-800 = 9x/10 
or, 
10x-9x=800 
or, 
x=800 
 
So, the original sot of product is Rs. 800 
and, 
Selling price is (10% in profit)  
Rs. 880

The correct answer for this is: 
Let CP =x 
!st SP =x+10%ofx=11x/10 
2nd SP =x-10%ofx =9x/10 
 
11x/10-9x/10=80 
x=400 
CP=400

10 % is given on SP not CP therfore ans 400 is wrong ...answer cannot be determined

(100+gain%):SP =(100-loss%):(SP-80) 
solving SP=440. 
CP=100*440/(100+10)=(100*440)/110=400. 
therefore cost price =Rs.400

Answer :Rs.800 
 
let the Cost Price of the product be x. 
on selling for 10% gain : 1.1*x 
Selling for Rs.80 less : x-80=0.9*x 
0.1*x=80 
and so x=Rs.800

The answer is 3D/(M(M-3))..coz, each share is first case:D/M. each share in second case :D/(M-3).so increase in share is : D/(M-3) - D/M

I think the answer is 400.

Let the price of the product is A.Then 1.1A-80=0.9A.
A=400

Let X be the original price of the product.
Let C be the cost of product.

The seller is gaining 10%. This means price is 10% more than cost.
x=1.1c

If the product is sold at Rs. 80 less then original price, he would suffer 10% loss.
So it will be 

(x-80) = 0.9c
or, 
1.1c-80 = 0.9c  (when x=1.1c)
or,
0.2c=80
or,
c=400 
 
And then x=1.1c -> x=440

Ans : let the cp be x and sp =y now profit % =(sp-cp) *100 /cp 10= (y-x) *100/x also 10=(x-(y-80))/x solving two x=400

sale price=cost price*(1+(%gain/100))

sale price=cost price*(1-(%loss/100))

first it was 10% gain and then 10% lessand ques says 80 less on SPso we get 80 = 20% of 110% i.e. 80 = 18%100% = 432 ans

as per queslet CP=100SP=11020% is the diff and 80 rs less from selling priceso 80 = 20% of 110%80 (nearly) = 18%so 432 = 100% ans(CP)

let sp be ycp be xgiven 10% profit on sp=> x=y*90/100and by selling at rs 80 less he got a loss of 10% on cp=> y-80=x*90/100 => y-80=y*90/100*90/100=> y(1-81/100)=80y=80*100/19x=7200/19=378.95

Let Cost Price be x, i.e. "1*x"

Since 10% profit is obtained, Selling Price is "1.1*x",

If Cost Price is less by 80, there is a loss of 10%,

:. x-80=0.9x

:. x=800 

naresh

given 10% gain on cellin price...so if x is s.p then 0.1x is profit ..so c.p=0.9x...(1)

now if 80 rs less to s.p====> s.p=(x-80)..loss is 10%..so x-80=0.9 c.p----(2)

solving 2 equations.

pankaj

• Jul 24th, 2006

 

answer is 400

we know that gain%=(s.p-c.p)100/c.p=10

so by solving this we get s.p/c.p=11/10

and loss% =(c.p-(s.p-80))100/c.p=10

and solving this by substituting the value of s.p/c.p=11/10

we get c.p as rs400

s=c(1+g/100)

s->selling price, c=cost price, g=gain percentage.

s=(11/10)c

(11/10)c=9c/10

c=400

cost price is 400

selling price =  10% of 80

that is 88

profit is 8

so cost price 72

The answer is supposed to be something like this:

0.9x = (x - 80) *1.1

x = 440

i think 880 is the right answer y because heis selling the item with10% profit first and then he is selling that with a loss of 10% that 10%loss is equal to 80/-
for 110% how much it is 880/-
ok bye

  let X be the actual price.

he sells that product at 10%losing and it is equal to X-80
i.e X-80=X*90/100
  10X-800=9X
  i.eX=800
 
The cost price is 800.

Its answer is 800 Rs
Cost price percentage = 100 %
Loss at 80 Rs = 10 %
if 10 % = 80 Rs; then
1 % = 8 Rs
100 % = 800 Rs
Cost price = 800 Rs (Answer)

hi

i give u genaralised answer
 
the question tells that if he sells the item at Rs.80 less he loose 10%

so if he want to loose all 100% he should sell that at Rs.800 less

so the cost price will be Rs.800

Take simple calculation by

Having  Cost price    then Selling price
              100X                    110x                   according given condition.

Now if sold 80 less than original s.p will have 10% loss.

s.p= 110x-80                                            

Therefore...  10 =  100X- (110X-80) * 100
                             -----------------------------
                                     100X
if solved x=4

therfore original c.p= 100X= 400.

let us assume cost of product as C, price of product as P

P-C=P/10 ...1

P-80-C=-(P/10) ....2

from equation 1and 2,

Price 400, Cost = 360
