20% of 900 = 180

45kg in 180 rupees

price of 1kg is 180/45 = 4rupees/kg

initial price is 4 = 5rs

{ }

Answer will be 105 : 56 : 50

Let investment of B is x for y months.

Then,
A's investment = 3x for 2y months

∴ Ratio of Profits of A and B- 

A : B = (3x × 2y) : (x × y)

= 6xy : xy = 6 : 1

Let the total profit = m.

Then,
B's share = (1/7)×m
⇒ m/7 = 6000
∴ m = 6000 × 7

Total Profit = Rs. 42000

∴ 20% of 42000 = Rs. 8400

Let the total investment = 12 units

Then Ram invested = 2 units

Rohit Invested = 4 units

Raju Invested = 6 units

Hence,

Ram: Rohit: Raju = 2 : 4 : 6 = 1:2:3

Ratio of investment = 8100 : 24300 : 21600 = 3 : 9 : 8
Sum of Ratio = 3 + 9 +8 = 20

Sunil profit share = 10800 - - - - - - - - - - (i)

Let the total profit = x

On the basis of investment; Sunil profit share = 9x/20 - - - - - - -- (ii)

Eq (i) & (ii) are equal

So,

9x/20 = 10800

x = 24000

((30 ×1) +(40×2)) : ((40×2)+(20×1)) : (10×3)

11 : 10 : 03 = ratio of profit

Let the total capital = 6x

We know, 33.33% = 1/3
and 25% = 1/4

ATQ,
A invests 33.33% of total capital = 6x/3 = 2x
Remaining Capital = 6x − 2x = 4x
B invests 25% of remaining = 4x/4 = x
and C invests the rest = 6x−2x−x = 3x 

Now,
Total profit of A+B+C = 162000
We know, If time is equal, the profit is divided in the ratio of Investment.
so,
6x → 162000
x → 27000

A’s share in profit = 2x → Rs. 54000

Profit

Required,

Let total profit be Rs. X.

After PMRF, remaining profit = () = (

Now, A’s share =

A.T.Q.

550 =

X = 1250

So, total profit = Rs. 1250

Profit sharing ratio of Sumit, Ravi and Puneet

= 45000 : 81000 : 90000

= 5 : 9 : 10

Sum of ratios = 5 + 9 + 10 = 24

Profit after charity = 4800 – 4800 × 30% = 4800 – 1440 = ₹3360

Share of Sumit = 3360 ×  = ₹700
