Answer 1

Answer:

Step-by-step explanation:

C.p-(100/90)*1530=1700

S.p-(120/100)*1700=2040

Answer 2

Ram should sell an article at Rs 1112 to gain 20%

GIVEN:- S.P= 1530; Loss = 10%; New profit = 10%

TO FIND:- New S.P

SOLUTION:-

Let the C.P be x

Loss % =

$\frac{loss}{c.p} \times 100$

By putting the values in the formula

$10 = \frac{s.p - c.p}{c.p} \times 100 \\ 10 = \frac{1530 - x}{x} \times 100$

By cross multiplication

$10x = 153000 - 100x \\ 10x + 100x = 153000 \\ 110x = 153000 \\ x = \frac{153000}{110} \\ x = 1390$

Let the new S.P be y

Profit % =

$\frac{profit}{c.p} \times 100 \\ = \frac{c.p - s.p}{c.p} \times 100$

By putting values in the formula

$20 = \frac{1390 - y}{1390} \times 100$

By cross multiplication

$20 \times 1390 = (1390 - y) \times 100 \\ 27800 = 139000 - 100y \\ 100y = 139000 - 27800 \\ 100y = 111200 \\ y = 1112$

Hence, Ram should sell an article at Rs 1112 to gain 20%
