@All.

I'll tell the simplest answer which is;

1) the given ratio of capital is 4:5.
After 3 months they withdraw,
Mean 4:5 = 760 is invested for three months.
A3 : B3
So (4*3):(5*3)=760 --> eq(1).

After three months they withdraw 1:4 and 1:5.
The mean part of 1:4 of 4 is 1.
1/4*4=1.

And part of 1:5 of 5 is also 1.
1/5*5 = 1.

Now subtract the withdrawal capital from A and B which is 1:1
A=> 4-1 = 3.
B=> 5-1 = 4.

And add into the eq(1).
A3:(A-withdraw)*7 = 12+21
B3:(B-withdraw)*7 = 15+28.
33:43 = 760,
76x = 760,
x = 10.

Now A's share is;
33 * 10 = 330.

@Mary.

Get the ratios of salaries of Anil, Bhuvans, and Chandras from the info you mentioned (45:18:14=77).
Given the total amount 77000/77*18=18000.
Hence B's salary is 18k.

@EKTA.

It's saying that at the end of 10 months, that's why as A & B both withdraw after 3 months so the remaining months will be 7.

Capitals=a:b=4:5.

let their investments as 4x,5x.
A:B=4x*10-(4x*(1/4)*7):5x*10-(5x*(1/5)*7),
= 40x-7x:50x-7x,
=33x:44x.

A's share= {33/(33+44)}*760=330.
So option A is correct answer.

@Mary.

Anil's sal=x;
Bhuvan's sal=y;
Chandra's sal=z;

As given in the que 2/5x=y;
7/9y=z;
x+y+z=77000;
5/2y+y+7/9y=77000;

After taking the lcm
45y+y+14y=77000*18,
60y=1386000,
y=23100.

So, this is the answer.

Can anybody solve this?

2/5th of Anil salary is equal to Bhuvans salary and 7/9th of Bhuvans salary is equal to Chandra's salary. If the sum of the salary of all of them is 77000. Then how much is Bhuvans salary?

After reducing the capital why we again multiply with 4x i.e (4x-1/4*4x).

Thanks for the given explanation.

I didn't get it. Please help me to get the answer.

Why 4x is multiply with 1/4?
