If by selling goods for 7 3432, 10% of their cost is gained, at what price should the
to gain 20%?​

Answer 1

Step-by-step explanation:

$\underline{\underline{\huge{\red{\texttt{Required Answer:}}}}}$

Let C.P of goods be ₹ x.

Then,

S.P = C.P + (10% of C.P)

$= x + \frac{10x}{100}$

$= \frac{100x+10x}{100} = \frac{110x}{100}$

But, S.P = ₹73432 (given)

$\therefore \frac{110x}{100} = 73432$

$\implies 110x = 73432 \times 100$

$\implies x = \frac{73432 \times 100}{110}$

$\implies x = 66756.36$

Hence C.P = ₹66756.36

Then,

Gain = ₹(73432 - 66756.36)

= ₹ 6675.64

$\therefore 10\% = 6675.64$

Then,

20% = ₹(6675.64 × 2)

= ₹ 13351.28

Hence,

S.P for 20% gain = ₹(C.P + 20%)

= ₹(66756.36 + 13351.28) = ₹ 80107.64

Answer 2

Answer:

Rs.3744.

Step-by-step explanation:

Let x be the cost of goods.

It is given that by selling goods for rupees 3432, 10% of their cost is gained.

x+\dfrac{10}{100}x=3432x+

100

10

x=3432

x+0.1x=3432x+0.1x=3432

1.1x=34321.1x=3432

Divide both sides by 1.1.

x=\dfrac{3432}{1.1}x=

1.1

3432

x=3120x=3120

The cost of goods is 3120.

Selling price for 20% gain is

3120+\dfrac{20}{100}(3120)=3120+624=37443120+

100

20

(3120)=3120+624=3744

Therefore, the selling price should be Rs.3744.
