Answer 1

Answer:

Joy bought 12 pens for Rs 12000

C.P for 1 pen = Rs 1000

S.P of 1 pen = Rs 1500

S.P for 12 pen = Rs 1500 X 12= Rs 18000

Profit= SP - CP = Rs 18000- 12000= Rs 6000

Profit Percent = 100 X profit / Cost price

Profit Percent = 100 X 6000/ 12000

Profit Percent = 100 X 1/2

Profit Percent = 50 %

Answer 2

ANSWER :

He got 50% profit.

EXPLANATION :

It is given that,

• C.P of 12 pens = Rs. 12, 000

Also,

S.P of 1 pen = Rs. 1500

S.P of 12 pen = 12 × 1500

= Rs. 18000

We know that,

Profit = S.P - C.P

= Rs. 18000 - Rs 12000

= Rs. 6000

Now,

Profit% = ( Profit/CP ) × 100

= ( 6000/12000 ) × 100

= 600/12

= 50%

Hence,

He got 50% profit.
