Answer 1

Answer:

A. B. O

4200x12 3oooxlO. 6 ooox8

+1800x2 .3oooo. 48 ooo

= 54000

ratio = 54:30:48=9:5:8

Xx9/22=1620

x =3960

Total Profit =Rs3960

Answer 2

The total annual profit is Rs 3960

Solution:

Given that,

A started a business by investing Rs. 4,200

After 2 months B joined by investing Rs. 3,000

At the end of 4 months from the start of the  business, O joined with an investment of Rs. 6,000

At the end of 10 months from the start of the business, A added an additional amount of Rs.  1800

Therefore,

The ratio of amounts invested by A, B and O are:

$(4200 \times 12 + 1800 \times 2 ) : (3000 \times 10) : (6000 \times 8)\\\\54000 : 30000 : 48000\\\\54 : 30 : 48\\\\Reduce\\\\9 : 5 : 8$

Thus the ratio of invested by A, B, O is 9 : 5 : 8

A share in the annual profit was Rs. 1620

Let "x" be the total annual profit

Then, we can say,

$x \times \frac{9}{9+5+8} = 1620\\\\x \times \frac{9}{22} = 1620\\\\x = 1620 \times \frac{22}{9}\\\\x = 3960$

Thus the total annual profit is Rs 3960
