A toy is sold for Rs. 220, what was the cost if the rate of profit was 10% of the cost?

A) Rs.196

B) Rs.198

C) Rs.200

D) Rs.210

Given Data 

S.P = 220     Gain=10%  C.P=?

We know that :

S.P=[ 100 +Gain]/100 * C.P 

We Have to find C.P, so re-arrange formula 

⇒ C.P= 100/[ 100 +Gain] * S.P

Putting given data:

⇒ C.P= 100/[ 100 +10] * 220

⇒ C.P=200

 

 

A man bought some toys at the Rs. 60 and sold them Rs.50. Find his loss percent?

A) 10%

B) 16.6%

C) 25.8%

D) 30%

As S.P<C.P , so we get loss 

Loss  = C.P-S.P 

          =60-50

         = 10

Now,

 Loss%= [ 100*Loss]/C.P 

            =[ 100*10]/60

            =16.6%

 

 

 

An article is purchased for Rs. 450 and sold for Rs. 495. Find the gain percent?

A) 10%

B) 20%

C) 25%

D) 30%

Given that: C.P=450 & S.P=495

When S.P is greater than C.P, we get Profit

Profit=S.P-C.P

Profit=495-450

Profit = 45 

Now ,

Gain% = [100*Gain]/C.P

             = [100*45]/450

             = 10%
