spent 50 on its repairs. If he sold it for
1200, find the profit per cent.​

Answer 1

Answer:

11.11 % is the profit %

Step-by-step explanation:

• Cost price or CP = ₹1030
• on repairing he spend = ₹50
• Now total cost is ₹1030 + ₹50 = ₹1080
• Sailing Price Or SP is = ₹1200
• Profit is ₹1200 - ₹1080 = ₹120
• Profit% = ( 120/1080 ) * 100 = 11.11 % (Ans.)

Answer 2

${\boxed{\underline{\tt{ \orange{Required \: \: answer \: \: is \: \: as \: \: follows:-}}}}}$

★GIVEN:-

• C.P = Rs. 1030

• Spent on it = Rs. 50

• S.P = Rs. 1200

★TO FIND :-

• Profit %

★FORMULA USED:-

• $\sf{Cost \: price \: = \: Bought \: price \: + \: repairs. }$

• $\sf{Profit = S.P - C.P }$

• $\sf{Profit \% = \frac{Profit}{C.P} × 100}$

★SOLUTION:-

➝Total C.P = Rs.( 1030 + 50 )

➝ Total C.P = Rs. 1080

As, S.P > C.P

So, the person will get profit.

➝Profit = S.P - C.P

➝ Profit = 1200 - 1080

➝ Profit = Rs. 120

➝$\sf{Profit \% = \frac{Profit}{C.P} × 100}$

$\sf{Profit \% = \frac{120}{108 \cancel{0}} × 10 \cancel{0}}$

$\sf{Profit \% = \frac{120}{108} \times 10}$

$\sf{Profit \% = \frac{ \cancel{1200}}{ \cancel{108}} }$

${ \boxed{ \underline{ \huge{ \color{teal}{ \bf{\sf{Profit \% = 11.11 \%}}}}}}}$

So, the profit % is 11.11%

★MORE TO KNOW:-

• A = P (1+ r/n)^nt

• C.I. = P(1 + R/100)^n -P

• I = Prt

• C = P [(1+r)^n -1]

• S.I. = P × R × T /100

• Amount = Principal + Compound Interest.

★HERE,

• C -- Compound Interest.

• P -- Principal (original balance)

• r -- rate per period

• n -- number of periods

• P -- principal sum

• T -- time

• A -- Future value
