Suppose B invested the money for N months.
Then the ratio of investment = (12 x 11 : 11 x N) = 12 : N
? 12/N = 4/1
? N = 3 months.
Ratio between the investment of Pramod and Vikas = 40000 x 12 : 60000 x 8
= 480000 : 480000 = 1 : 1
Total profit = Rs. 16000
share of Vikas in profit = 16000/2 = Rs. 8,000
Let the saving of A and B are 4p, 5p and the share in cost of gift are 3q, 4q respectively.
According to the question,
For A, 4p - 3q = (2/3) x 4p
? p = 9q/4 ..... (i)
For B, 5p - 4q = 145
? 5 x (9q/4) - 4q = 145 .....[by Eq. (ii)
? q = 20
? Cost of gift = 3q + 4q = 7 x 20
= ? 140
Given ratio of employee = 9 : 13 : 18
Let number of A's emplouees = 9k
Number of B's employees = 13k
and number of C's employees = 18k
According to the question
18k = 54
? k = 3
? Number of employee of type A = 9 x 3 = 27
Similarly, Wages of every employee of types A = 10/7 x 1400 = ? 2000
Required wages = 27 x 2000 = ? 54000
Let the person have ? N
Then shares of elder don = ? 2N/5
and share of younger son = ? 3N/10
According to the question,
2N/5 - 3N/10 = 2000
? N/10 = 2000
? N = 20000
Remaining amount saved in trusts
= 1 - (2N/5 + 3N/10 ) = 1 - (4N + 3N)/10
= 1 - 7N/10 = 3N/10 x 20000 = 6000
given that A : B : C = 3 : 5: 2
? Share of C = [2/(3 + 5 +2)] x 6000
= (2/10) x 6000 = ? 1200
Amount given to A= 9k + 26
Amount given to B = 13k + 28
and amount given to C = 8k + 32
According to the question,
(9k + 26) + (13k + 28) + (8k + 32) = 2186
? 30 k + 86 = 2186
? 30 k = 2100
? k = 70
Hence, amount given to A = 9k + 26 = 9 x 70 + 26
= 630 + 26 = ? 656
Suppose B invested Rs. x for y months.
Then A's investment is Rs. 3x for 2y months.
Ratio of investment of A and B = 6xy : xy = 6 : 1.
Now B's share = Rs. 4,000
? A's share = Rs. 24, 000
Hence, Total profit = Rs. 28,000
Ratio of shares = 27000 : 81000 : 72000 = 3 : 9 : 8
If Ram's share is Rs. 9 then total profit = Rs. 20
If Ram's share is Rs. 36000 then total profit = Rs. (20/9) x 36000
= Rs. 80000
Let C's share = Rs. N
Then B's share = Rs. N/2
and A's share = Rs. N/4
? A : B : C = N/4 : N/2 : N = 1 : 2 : 4
Hence C's share = Rs. 700 x (4/7) = Rs. 400
Ratio of their shares = (6000 x 12) : (4000 x 6) = 3 : 1
? Madhu's share = Rs.5200 x (1/4)
? 30000/N = 2/3
? 2N = 90000
? N = 45000
