Rs. 8500
Rs. 9000
Explanation:

Let B's capital be Rs. x.

 Then, 3500 x 12 = 2 7x 3 14x = 126000 x = 9000.

Here, 3500/B * 12/7 =2/3 = 9000.

Partnership formula
Partnership formula

Ratio of investment * time = Ratios of profit

3500 * 12 : x (unknown) * 7 = 2 k : 3 k.

I have used t as it's a substituted ratio

42000 : 7 x = 2k : 3k.

To find the value of k;
42000 = 2 k.
k = 42000/2 = 21000.

To find the value of x

7x = 3k,
7x = 3 * 21000
x = (3*21000)/7.
x = 9000.

Can you explain 12*3500 /7x, what is the answer?

Pavan said:   1 year ago
Note: According to the question we can say that A invested for 12months and B invested after 5 months it means 12months-5= B invested for 7 months.

Then time ratios of A:B = 12:7

Investment = profit/ tim -> to find Investment.
Profit ratios 2 : 3.
Times ratios 12:7.

2/12 : 3/7 do cross multiplication.

ie. 2x7: 12x3.
14: 36 = 7 : 18.
Here
7Parts == 3500.
1p = 500 then.
18p = 18 x 500 = 9000.

But B joined A after 5 months, which means that A had completed his 10 months of investment.

Thus the equation should be like:
(3500*10/x*5) = 2:3.
Right?

A starts a buisness after 5 months for 3500 rupees.
B joins with A.

A has start after 5 months and remaining months is' 7' why because 1 year =12 months. Let we take 7 is for B.

Then (3500*12/7) =2/3. For 2/3 is given for ratio.
14x=126000.
=>12600/14.
X=9000.

First of the After a year write a question is 12 is month wise.
3500*12/7x = 2/3.

By cross multiplying, we get;

3500*12=4200 multiple by 3 (42000*3)= 126000.
7 multiple by 2 (7*2) =14.
