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 |

S.P = 2X => Double
C.P= X
P= (X-2X)3 => Triple
= 3X - 2X,
P= X.
Profit% = Profit/C.P × 100.
X/X ×100,
100.
Then, Profit% = 100.
C.P= X
P= (X-2X)3 => Triple
= 3X - 2X,
P= X.
Profit% = Profit/C.P × 100.
X/X ×100,
100.
Then, Profit% = 100.

SP = CP + P
If sp -> 2sp,
then p-> 3p.
sp - cp gives profit,
2(sp) - cp gives total profit which equal to 3p(profit) -> eqn 1
2(cp + p) - cp = 3p,
2cp + 2p -cp = 3p,
cp = p.
p->cp
p equals to cp, which is 100%.
If sp -> 2sp,
then p-> 3p.
sp - cp gives profit,
2(sp) - cp gives total profit which equal to 3p(profit) -> eqn 1
2(cp + p) - cp = 3p,
2cp + 2p -cp = 3p,
cp = p.
p->cp
p equals to cp, which is 100%.

Let cp = 100
sp = 200.
Profit = 200 - 100 = 100,
Profit % = (100/100) * 100 = 100% ( Ans).
sp = 200.
Profit = 200 - 100 = 100,
Profit % = (100/100) * 100 = 100% ( Ans).

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%.

Let c.p be x.
Let s.p be y.
profit = s.p - c.p.
3(y-x) = 2y-x,
3y-3x = 2y-x,
y = 2x.
Profit% = s.p-c.p/c.p * 100.
Put y = 2x here,
3(2x-x) = 2(2x)-x/x * 100,
6x-3x = 4x - x/x * 100,
3x = 300,
x = 100.
Let s.p be y.
profit = s.p - c.p.
3(y-x) = 2y-x,
3y-3x = 2y-x,
y = 2x.
Profit% = s.p-c.p/c.p * 100.
Put y = 2x here,
3(2x-x) = 2(2x)-x/x * 100,
6x-3x = 4x - x/x * 100,
3x = 300,
x = 100.

C.P = x.
S.P = 2x.
P = S.P - C.P.
=> 2x - x = 3.
=> x = 3.
C.P = 3.
S.P = 6.
P = S.P - C.P.
= 6 - 3.
=3.
=> P = 3.
P%= P/C.P(100)
= 3/3 (100).
= 1(100),
= 100%.
P% = 100%.
S.P = 2x.
P = S.P - C.P.
=> 2x - x = 3.
=> x = 3.
C.P = 3.
S.P = 6.
P = S.P - C.P.
= 6 - 3.
=3.
=> P = 3.
P%= P/C.P(100)
= 3/3 (100).
= 1(100),
= 100%.
P% = 100%.
