Let their investments be Rs. x for 12 months, Rs. y for 8 months and Rs. z for 6 months respectively.
Then, 12x : 8y : 6z = 4 : 6 : 8
Now, 12x/8y = 4/6 <=> 9x=4y <=> y=9x/4
And, 12x/6z = 4/8 <=> 4x=z <=> z=4x
Therefore, x : y: z = x : 9x/4: 4x = 4 : 9 : 16
Given ratio of initial investments = = 105 : 40 : 36.
Let the initial investments be 105x, 40x and 36x.
= 1680x : 480x : 432x = 35 : 10 : 9.
Hence, B's share = = Rs. 4000.
Let O's share = Rs. P
=> N's share =
M's share =
Let the ratio amount be 'p'
7p - 3p = 2700
4p = 2700
p = 675
R's Share = 675 × 6 = Rs. 4050
A : B : C = 7 : 8 : 11.
Hire charges paid by B = Rs. (520 * 8/26) = Rs. 160.
Ratio of investments of A, B & C =>
Share of C = 1530
Share of B = 765
Share of A = 1020
Let the amount invested by saketh = RS. p
Now, that of sandeep = 20,000 x 6
saketh = 12 x p
Ratio of their earnings = 120000 : 12p = 6000 : (9000 - 6000)
=>
Hence, the amount investe by saketh = Rs. p = Rs. 5000.
A : B = 3 : 2 => B : A = 2 : 3 = 4 : 6 and A : C = 2 : 1 = 6 : 3.
So, B : A : C = 4 : 6 : 3 or A : B : C = 6 : 4 : 3.
B's share = Rs. (157300 x 4/13 ) = Rs. 48400.
Let C = x.
Then B = x/2
and A = x/4
A:B:C = 1:2:4.
C's share Rs.[(4/7)*700) = 400
Given A & B in partnership
A Invests 116000 for 12 months
=> A's share = 116000 x 12 = 13,92,000
B Invests for 6 months
=> B's share = 144000 x 6 = 8,64,000
Their Ratio = 1392 : 864 = 29 : 18
Let the Annual profit = P
Given B's share = Rs. 9000
=> 18/47 x P = 9000
=> P = 9000 x 47/18
=> P = 23,500
Hence, Overall profit = P = Rs. 23,500
The ratio of A & B investments = (3x8 + 2x4):(4x8 + 5x4)
=> 8:13
=> 8/21 x 630 = 240.
