The respective ratio of Sita's Riya's and Kunal's monthly incomes is 84 : 76 : 89. If riya's annual income ? 456000, then what is the sum of Sita and Kunal's annual incomes? (In some cases monthly income and in some cases annual income is used).?

4 leaps of cat = 3 leaps of dog
? 1 leap of cat = 3/4 leap dog
Cat takes 5 leaps for every 4 leaps of dog
? Required ratio = (5 x Cat's leap ) : ( 4 x Dog's leap)
= (5 x 3/4 dog's leap) : (4 x Dog's leap)
= 15 : 16

According to the question
Expenses ? (income)²
? 9000 = K (15000 )²
? K = 9000/(15000)²
= 1/25000
Again E = K x 1²
? 1 = K x 1² [? exenses = income]
? 1 = 1/K = 25000
? Required answer = ? 25000

Ratio of salaries
Akash : Babloo : Cintu 2 : 3 : 5
Let the common ratio be 'k'
Then, salaries of Akash, Babloo and chintu will be 2k, 3k and 5k, respectively.

Now, 15% increase in Akash's salary = 15% of 2k
= 15 x 2k/100 = 0.3k
New salary = 2k + 0.3k = 2.3k

Also, 10% increase in Babloo's salary = 10% of 3k
= 10 x 3k/100 = 0.3k
? New salary = 3k + 0.3k = 3.3k

Again, 20%increase in Chintu's salary = 20% of 5k
= 20 x 5k/100 = 1k
New salary = 5k + k = 6k

? New ratio = Ratio of new salaries = 2.3k : 3.3k : 6k
On multiplying with 10 and dividing by k ratio will be 23 : 33 : 60.

2A/5 + 40 = 2B/7 + 20 = 9C/17 + 10 = K
Then, A = (5/2) x (K - 40), B = (7/2) x (K - 20), C = (17/9) x (K - 10)

According to the question, A + B + C = 600
? (5/2) x ( K - 40) + (7/2) x (K - 20) + (17/9) x (K - 10) = 600
? 45 x (K - 40 ) + 63 x (K - 20) + 34 x (K - 10) = 10800
? 45K - 1800 + 63K - 1260 + 34K - 340 = 10800
? 142K - 3400 = 10800
? 142K = 10800 + 3400
? 142K = 14200
? K = 14200/142 =100
? B = (7/2) x (K - 20) = (7/2) x (100 - 20)
= (7 x 80)/2 = 7 x 40
= ? 280

According to the question.
(46k +30) + (41k + 30) + (34k + 25) = 2505
? 121k = 2505 - 85 = 2420
? k = 2420/121 = 20
? Number of coins received by Parat = 41k + 30
= 41 x 20 + 30 = 850

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

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

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 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

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
