3.
If selling price is doubled, the profit triples. Find the profit percent.
Answer: Option
Explanation:
Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x) 
y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
 Profit % = |
 |
x | x 100 |  % = 100% |
| x |

No need that much solution.
Let CP = 1 Rs.
Then SP = 2 rs (because double).
Leave profit is triple. no need to take,
That's why profit % is 100% (because double).

Let the selling price be SP.
Cost price be CP and profit be P.
As P=SP-CP.
For given condition, 3P= 2SP-CP
3 (SP-CP)=2SP-CP
SP=2CP
Profit% = (SP-CP) * 100/CP
=100%.

Profit% = (SP-CP) * 100/CP
=100%.

Both are profits s.p is y and c.p is x then profit is y-x. And if profit tripls then 3(Y-X) is profit and new selling price is 2y then profit is 2y-x.

Just take cp 100%.
Then sp=100%+profit.
2 times of sp = 200%+2p == cp+3 (p)here profit only triple not cost price(100% only).
200%+2p=100%+3p.
From that;
P=100%.
Then sp=100%+profit.
2 times of sp = 200%+2p == cp+3 (p)here profit only triple not cost price(100% only).
200%+2p=100%+3p.
From that;
P=100%.

Assume 40 is cost price,
80 as selling price,
120 is the profit.
As per the question, we have a formula for profit% = gain * 100/cost price = 40 * 100/100 = 100.

A table is sold at a profit of 20%. If the cost price and selling price are rs200 less, the profit would be 8%more, find the cost price.
Can anyone solve this?

Assume cp = 1 and sp = 2 then profit = 1.
If sp double means sp = 4 then profit = 4-1=3(it became triple).
So,
Formula----> profit/cp * 100 = 1/1 * 100 = 100.
If sp double means sp = 4 then profit = 4-1=3(it became triple).
So,
Formula----> profit/cp * 100 = 1/1 * 100 = 100.

If,cp = x.
Sp = 2x.
Profit = 3x.
Then,sp>cp
2x - x
1st,2x - x = 3
X = 3.
2nd, profit % = 2x-x/x*100,
= 200x - 100x/x.
= 600-300/3.
= 300/3.
= 100%.
Sp = 2x.
Profit = 3x.
Then,sp>cp
2x - x
1st,2x - x = 3
X = 3.
2nd, profit % = 2x-x/x*100,
= 200x - 100x/x.
= 600-300/3.
= 300/3.
= 100%.

C.P = 100.
S.P = 200(i.e S.P doubled).
Profit = S.P - C.P.
=>200-100 = 100.
Profit % = (profit*100)/C.P.
= (100*100)/100.
= 100.
S.P = 200(i.e S.P doubled).
Profit = S.P - C.P.
=>200-100 = 100.
Profit % = (profit*100)/C.P.
= (100*100)/100.
= 100.

PROFIT = 3(Y-X)= (2Y-X)
= 3Y-3X-2Y+X
= 1Y-2X
(i.e)Y=2X : Profit = (Y-X)(i.e) =(2x-x)=Rs.x
Profit% = C.P/profitX100= X/X*100=100%.
FROM HERE EXPLAIN CLEARLY.
= 3Y-3X-2Y+X

(i.e)Y=2X : Profit = (Y-X)(i.e) =(2x-x)=Rs.x
