H. Four businessman invested a sum of Rs. 250000 in the ratio of 3:5:7:10 to start
a new bushess
i) Find the sum invested by each of them
i At the end of the year, if they gained
Rs 50,000 divide the profit among them in the ratio of their shapes
.

The answers are in solutions.

Step-by-step explanation:

(i) The amount invested by each businessman is;

1^st businessman invested:

Rs. 30,000

2^nd businessman invested:

= Rs. 50,000

3^rd businessman invested:

= Rs. 70,000

4^th businessman invested:

= Rs. 100,000

(ii) The profit each one of them got is;

1^st businessman got:

= Rs. 6,000

2^nd businessman got:

= Rs. 10,000

3^rd businessman got:

= Rs. 14,000

4^th businessman got:

= Rs. 20,000

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
