(a) Gardening shears bought for Rs.250 and sold for Rs. 325.

(b) A refrigerator bought for Rs. 12,000 and sold at Rs.13,500.

(c) A cupboard bought for Rs. 2,500 and sold at Rs.3,000.

(d) A skirt bought for Rs. 250 and sold at Rs.150.

Answer :

(a) Here, CP = Rs.250

SP = Rs. 325

Since SP > CP

\(\therefore \)Profit = SP – CP

= Rs. 325 – Rs. 250 = Rs. 75

\(\therefore \) profit% = \(\frac{profit ×100}{CP} \)

= \(\frac{75}{100} \) ×100 = 30 %

(b) Here, CP = Rs.12000

SP = Rs. 13500

Since SP > CP

\(\therefore \)Profit = SP – CP

= Rs. 13500– Rs. 12000 = Rs. 1500

\(\therefore \) profit% = \(\frac{profit ×100}{CP} \)

= \(\frac{1500}{12000} \) ×100 = \(12\frac{1}{2} \)%

(c) Here, CP = Rs.2500

SP = Rs. 3000

Since SP > CP

\(\therefore \)Profit = SP – CP

= Rs. 3000– Rs. 2500 = Rs. 500

\(\therefore \) profit% = \(\frac{profit ×100}{CP} \)

= \(\frac{500}{2500} \) ×100 = 20%

(d) Here, CP = Rs.250

SP = Rs. 150

Since SP < CP

\(\therefore \)loss = CP– SP

= Rs. 250– Rs. 150 = Rs. 100

\(\therefore \) LOSS% = \(\frac{LOSS×100}{CP} \)

= \(\frac{100}{250} \) ×100 = 40%
