10.c)

__Solution__= 5x × 12 + 8x × 12 = 156x

Total equivalent capital of B for 1 month

= 6x × 24 = 144x

Total equivalent capital of C for 1 month

= 8x × 12 + 4x × 12 = 144x

Required ratio

= 156x : 144x : 144x

= 13 : 12 : 12

2.Ratio of the equivalent capitals of Prakash, Sunil and Anil for 1 month

= (11 × 36) : (16.5 × 36) : (8.25 × 36)

= 4 : 6 : 3

Anil's share in the profit

= [3/(4 + 6 + 3)] × 19.5 = Rs.4.5 lakhs

50% of 4.5 lakhs = Rs.2.25 lakhs

3.Required difference

= [(7/11 × 2) - (4/11 × 3)] × 73689

= Rs.13398

4.Ratio of equivalent capitals for 1 month

= (18000 × 12) : (24000 × 8) : (30000 × 6)

= 18 : 16 : 15

Sum of ratios = 18 + 16 + 15 = 49

Let, the total profit be Rs.x, then

C's profit = 15x/49

now, 15x/49 = 1845

or, x = (1845 × 49)/15 = 6027

5.C's investment = Rs.x thousand

Therefore, ratio of their equivalent capitals for 1 month

= (12 × 24000) : (12 × 28000) : (8 × x × 1000)

= 36 : 42 : x

Sum of ratios = 78 + x

C's share = x/(78+x) × 19950

or, (19950x)/(78 + x) = 7600

or, x = 59280/1235 = Rs.48000

6.Let the total money be x

Half of the total money goes to wife = x/2

2/3rd of the remaining x/2 = x/3 is divided equally among three sons.

The share of each son = 1/3 × x/3 = x/9 and (x/2 - x/3) = x/6 is divided equally among four daughters.

The share of each daughter = 1/4 × x/6 = x/24

Now, x/24 = 20000

or, x = 480000

The share of each son

= 480000/9 = Rs.53,333.33

7.The ratio of capital invested by each partner for 1 month in order to get the same profit

= (36 × 50000) : (30 × 80000)

= 3 : 4

Share of Sunetra = (3/7) × 24500 = Rs.10500

8.Shivkumar's equivalent capital

= (25000 × 3) + (10000 × 2) + (10000 × 1)

= 105000

Rakesh's equivalent capital

= 35000 × 2 = 70000

Suresh's equivalent capital

= 35000 × 1 = 35000

Total profit of Rs.150000 will be distributed in the ratio of their equivalent capitals.

Shivkumar : Rakesh : Suresh

= 105 : 70 : 35

= 3 : 2 : 1

Rakesh's share = [2/(3 + 2 + 1)] × 150000 = Rs.50000

9.Gaining ratio

= (3/5 - 4/9) : (2/5 - 2/9)

= 7 : 8

10.B's investment = (16000 × 5)/8 = Rs.10000

Ratio of equivalent capitals of A, B and C for 1 month

= (3 × 16000 + 9 × 14000) : (10000 × 9) : (9000 × 6)

= 29 : 15 : 9

Now, 9 ≡ 1026

or, 29 = (1026 × 29)/9 = Rs.3306
