**Solutions:**

S1. Ans.(d)

S2. Ans.(b)

S3. Ans.(b)

S4. Ans.(a)

S5. Ans.(c)

S6. Ans.(c)

Sol. Here, purchasing price for mobile phone = Rs. 12000

Profit percentage = 8%

∴ Selling price =12000((100 + 8)/100)

= 12000×108/100 = Rs. 12960

Again, purchasing price for refrigerator = Rs. 10000

Loss percentage = 12%

∴ Selling price =10000×((100-12)/100)

=10000×88/100 = Rs. 8800

Now, total SP = 12960 + 8800

= Rs. 21760

Total CP = Rs 22000

∴ Total loss = 22000 – 21760 = Rs. 240

S8. Ans.(d)

Sol. Here, cost price of 25 kg of rice

= 25 × 32 = Rs. 800

Cost price of 15 kg of rice

= 15 × 36 = Rs. 540

Total quantity of rice

= 25 + 15 = 40 kg

Total cost of rice = 540 + 800

= Rs. 1340

Selling price of rice

= 40 × 40.20 = Rs. 1608

∴ Profit = 1608 – 1340 = Rs. 268

Profit percentage =268/1340×100=20%

S9. Ans.(a)

Sol. Let the selling price of each notebook be Rs. 1

Then, selling price of 12 notebooks = Rs. 12

Profit = Selling price of 4 notebooks = Rs. 4

Cost price = Selling price – Profit

= 12 – 4 = Rs. 8

Profit percentage =4/8×100=50%

S10. Ans.(a)

Sol. Here, selling price of article

= Rs. 15000

Discount = 10%

Then, selling price

=15000-15000×10/100

= 15000 – 1500

= Rs. 13500

Profit = 8%

Then, cost price = (Selling price × 100)/(100 + Profit%)

=(13500 × 100)/108

= 125 × 100 = Rs. 12500
