model 4 mixed discount problems of marked price Section-Wise Topic Notes With Detailed Explanation And Example Questions

Answer: (c)

C.P. = Rs.900, Gain = 10%

S.P. = Rs.$(110/100 × 900)$ = Rs.990

Let the marked price be x.

$90/100 x$ = 990

$x = {990 × 100}/90$ = Rs.1100

Using Rule 6,

Here, D = 10%, C.P. = Rs.900,

R = 10%, M.P. = ?

$\text"MP"/\text"CP" = {100 + r}/{100 - D}$

$\text"MP"/900 = {100 + 10}/{100 - 10}$

M.P. = $110/90 × 900$ = Rs.1100

Answer: (d)

CP of the article for Ravi

= $660 × 100/110$ = Rs.600

Ravi bought the article at the discount of 25%

75% of marked price = Rs.600

Marked price

= ${600 × 100}/75$ = Rs.800

Answer: (a)

Let marked price of toy be x

S.P. = $x × 77/100 = {77x}/100$

C.P. = $x × 77/100 × 100/110 = {7x}/10$

${77x}/100 - {7x}/10 = 56$

${7x}/100 = 56$

$x = {100 × 56}/7$ = Rs.800

Answer: (c)

If the marked price of T.V. be x, then,

${x × 5}/100$ = 500

$x = {500 × 100}/5$ = Rs.10000

Initial S.P. of T.V.

= ${10000 × 80}/100$ = Rs.8000

Answer: (a)

If the marked price of the article be x, then

96% of x = 1920

${x × 96}/100 = 1920$

$x ={1920 × 100}/96$ = Rs.2000

Using Rule 2,

S.P. = Rs.1920 D = 4% M.P. = ?

M.P. = $\text"S.P. × 100"/{100 - D}$

= ${1920 × 100}/{100 - 4}$

= ${1920 × 100}/96$ = Rs.2000

Answer: (d)

Let the printed price of the article be Rs.100

Discount = 40%

C.P. = Rs.(100 - 40) = Rs.60

S.P. = Rs.100

Gain % = $40/60 × 100$

= $200/3 = 66{2}/3$%
