Question

find loss percentage when SP is Rs 15000 and CP is Rs 20000​

Answer 1

Step-by-step explanation:

S.P= 15000

C.P=20000

LOSS=C.P-S.P

=5000

LOSS%=5000×100÷20000

=25%

Answer 2

Answer:

Finding CP  when SP and Profit or Loss Percent are given

Solution:

Let c.p = 100Asthereisprofit100Asthereisprofit120

Let the c.p of the scooter be xNowmakeproportionsas100/x=120/18000Crossmultiply120x=100.18000120x=1,800,000So,x=1,800,000/120x=xNowmakeproportionsas100/x=120/18000Crossmultiply120x=100.18000120x=1,800,000So,x=1,800,000/120x=15000

Hence the cost price of the scooter is 15000.

2) By selling an AC for15000.  _________________________________________________________________ 2) By selling an AC for 20,000, I lose 20%. What did I pay for it?

 Solution:

We have S.P. = 20,000andloss=20Letc.p=20,000andloss=20Letc.p=100

As there is loss % as 20 so s.p = 100 - 20 = 80Letthec.pofthescooterbe80Letthec.pofthescooterbex

Now make proportions as

100/x = 80/20,000

Cross multiply

80x = 100 . 20,000

80x = 2,000,000

So, x = 2,000,000/80

x = 25000HencethecostpriceoftheACis25000HencethecostpriceoftheACis25,000.

3) SP = $450 and profit % = 50, find CP.

Solution :

Let c.p = 100Asthereisprofit100Asthereisprofit150

Let the c.p of the scooter be xNowmakeproportionsas100/x=150/450Crossmultiply150x=100.450150x=45,000So,x=45,
