Question

Find the Cost price when : S.P. = rs 1500 and gain = 20% tell me the answer first I mark you as brainliest and tell me the answer step by step and send me the photo ​

Answer 1

Answer:

(i) CP = Rs.. 1200, SP = Rs.. 1350

CP < SP. So, profit.

Profit = Rs. (1350 - 1200) = Rs. 150

(ii) CP = Rs. 980, SP = Rs. 940

CP > SP. So, loss.

Loss = Rs. (980 - 940) = Rs. 40

(iii) CP = Rs. 720, SP = ?, profit = Rs. 55.50

Profit = SP - CP

⇒ Rs. 55.50 = SP - Rs. 720

⇒ SP = Rs. (55.50 + 720) = Rs. 775.50

(iv) CP = ?, SP = Rs. 1254, loss = Rs. 32

⇒ Loss = CP - SP

⇒ Rs. 32 = CP - Rs. 1254

⇒ CP = Rs. (1254 + 32) = Rs. 1286

Answer 2

$\huge\rightarrowtail{\texttt{\red A\orange N\purple S\blue W\green E\red R}}$

Here we know the S.P and Gain % and we have to find the Cost Price.. So Let's Solve!

$\:$

$\star$ Formula Used :

$\rightarrowtail$ CP = ( SP * 100 ) / ( 100 + percentage profit)

$\:$

$\rightarrowtail$ 100/100 + 20%

$\rightarrowtail$ 100/120

$\rightarrowtail$ 100/120 × 1500

$\rightarrowtail$ 1250

$\green{\implies}$ Hence, The Cost Price is Rs.1250
