Answer :-

Rs.2000

Explanation :-

Given :

Discount = 17.5%

Cost Price = Rs. 1200

Profit = 37.5%

To Find :

Marked price,MP = ?

Solution :

We know,

\boxed{\sf{}\dfrac{SP\times 100}{100-Discount}}

100−Discount

SP×100

We don’t know selling price,so let’s find out it first.

Selling Price,

\sf{}:\implies \dfrac{CP\times(100+Profit)}{100}:⟹

100

CP×(100+Profit)

\sf{}:\implies \dfrac{1200\times(100+37.5)}{100}:⟹

100

1200×(100+37.5)

\sf{}:\implies \dfrac{1200\times(1137.5)}{100}:⟹

100

1200×(1137.5)

\sf{}:\implies \dfrac{165000}{100}:⟹

100

165000

\sf{}\therefore Rs.1650∴Rs.1650

Therefore,selling price is equal to Rs.1650

So marked price,

\sf{}:\implies\dfrac{1650\times 100}{100-17.5}:⟹

100−17.5

1650×100

\sf{}:\implies\dfrac{165000}{100-17.5}:⟹

100−17.5

165000

\sf{}:\implies\dfrac{165000}{82.5}:⟹

82.5

165000

\sf{}\therefore Rs.2000∴Rs.2000

Hence, marked price is equal to Rs.2000

Answer 2

$\huge{\mathfrak{\red{Answer:-}}}$

given y- axis divides the line segments joining (3,5),(-4,7)

let us consider A(3,5) and B(-4,7)

The A,B value consider as zero so,

according to ratio formula,X=m(x2)+n(X1)/m+n,y=m(y2)+n(y1)/m+n

so here we take,

• X1=3
• y1=5
• x2=-4
• y2=7 by this we substitute in formula we get

0=m(-4)+n(3)/m+n

y=m(7)+n(5)/m+n

0= -4m+3n

4m=3n== m/n=3/4===m:n =3:4

so,the answer is 3:4

I hope this helps u dear ☺️
