Answer: (d)

Let CP of 8 quintal rice = Rs. x

∴ CP of 1 quintal rice = Rs. $x/8$

∴ SP of rice 3 quintal of rice at 10% profit

= ${3x}/8 + {3x}/8 × 1/10 = {3x}/8 + {3x}/80 = {33x}/80$

SP of 3 quintal rice without profit or loss = Rs. ${3x}/8$

SP of 2 quintal rice at 5% loss = ${2x}/8 - {2x}/8 × 5/100$

= $x/4 - x/{4 × 20} = {19x}/{4 × 20} = {19x}/80$

∴ Total SP = ${33x}/80 + {3x}/8 + {19x}/80$

= ${33x + 30x + 19x}/80 = {82x}/80$

∴ Profit = $\text"SP - CP"/\text"CP" × 100 = {{82x}/80 - x}/x$ × 100

= ${(82 - 80)x}/{80x} × 100 = 2/80$ × 100 = 2.5%

Answer: (b)

15% of x = 45

$x = {45 × 100}/15$ = 300

Answer: (c)

Price = ${20 × 10}/{(100 - 20) × 5} = {20 × 10}/{80 × 5}$ = 50 paise

Answer: (b)

CP of television set = SP × $100/{100 + \text"Profit%"}$

= Rs. $({11500 × 100}/125)$ = Rs.9200

Answer: (b)

If the C.P. of article be Rs. x, then

$x × 116/100 + 200 = {x × 120}/100$

⇒ $x × 4/100 = 200$

⇒ $x × {200 × 100}/4$ = Rs. 5000
