A shopkeeper expects a gain of 22.5% on his cost price. If in a week, his sale was of Rs. 392, what was his profit?
Answer: Option
Explanation:
| C.P. = Rs. |  |
100 | x 392 |  |
= Rs. | |
1000 | x 392 | |
= Rs. 320 |
| 122.5 | 1225 |
Profit = Rs. (392 - 320) = Rs. 72.

Cost Price: (C.P.)
C.P. =100x S.P.
(100 + Gain %)

Hi to all
Let profit be 100
Given that gain is 22.5%
122.5--- 392
100---?
ie,(100*392)/122.5=320
profit=392-320=72

cp=?,sp=392,profit=22.5%
cp=(100/(100+profit%)*sp)
=100/(100+22.5)*392
=100/122.5*392
=1000/1225*392
cp=320
if profit=sp-cp
=392-320
profit=72
cp=(100/(100+profit%)*sp)
=100/(100+22.5)*392
=100/122.5*392
=1000/1225*392
cp=320
if profit=sp-cp
=392-320
profit=72

We have simple formula
s.p=(100+profit%)*c.p/100
392=(100+22.5)*c.p/100
392=(125)*c.p/100
392/122.5=c.p/100
3.2=c.p/100
therefore c.p=320
profit=s.p-c.p
=392-320
= 72
therefore profit is rs.72
s.p=(100+profit%)*c.p/100
392=(100+22.5)*c.p/100
392=(125)*c.p/100
392/122.5=c.p/100
3.2=c.p/100
therefore c.p=320
profit=s.p-c.p
=392-320
= 72
therefore profit is rs.72

Let profit is x
s.p. = 392
c.p. = 392-x
now profit/c.p. = 22.5%
x/(392-x) = 22.5/100
x/392 = 22.5/122.5
solving this we get x = 72
s.p. = 392
c.p. = 392-x
now profit/c.p. = 22.5%
x/(392-x) = 22.5/100
x/392 = 22.5/122.5
solving this we get x = 72
