BRs.81005

CRs.60000

DRs.65007

Nithin ? undefined

Correct answer is: Rs.75000

Explanation:

Debt = 400X
Equity = 500X
Total = 900X
Earning = 30% of 900X = 270X
Total amount of money reinvested = 1170X
Debt = 6/13*1170X = 540X
Equity = 7/13 * 1170X = 630X
630X = 94500
500X = 500/630 * 94500 = 75000

The respective ratio of the present ages of a mother and daughter is 7 : 1. Four years ago the respective ratio of their ages was 19:1. What will be the mother's age four years from now ?

A42 years

B38 years

C46 years

D36 years

Nithin ? undefined

Correct answer is: 46 years

Explanation:

Let the present ages of mother and daughter be x and y respectively.

\(\frac{y}{x}=\frac{1}{7} \implies x= 7y\)

\(\frac{y-4}{x-4} = \frac{1}{19} \implies 19y - 76 = x - 4 \implies x = 19y - 72 \)

\(\implies 7y = 19y - 72 \implies y = \text{6 and x }= 42\)

Age of mother 4 years from now = 42 + 4 = 46

The age or Khushi and Jagriti are in the ratio of 5 : 8 respectively. After 8 years the ratio of their age will be 3 : 4. What is the difference in their age?

A16 years

B8 years

C10 years

DNone of these

Nithin ? undefined

Correct answer is: None of these

Explanation:

Let the present age of Khushi and Jagriti be 5x and 8x years respectively.
After 8 years,

\(\frac{5x+8}{8x+8}=\frac{3}{4}\)

=> 24x + 24 = 20x + 32
=> 4x = 32 - 24 = 8

=> x = 8×4 = 2

Requtred difference = (8x - 5x) years = 3x

= 3×2 

= 6 years

A sum of money is divided among A, B, C and D in the ratio of 3 : 5 : 9 : 13 respectively. If the share of C is Rs.2412 more than the share of A, then what is the total amount of money of B and D together?

ARs.4,422

BRs.7,236

CRs.6,030

DRs.4,824

Nithin ? undefined

Correct answer is: Rs.7,236

Explanation:

Let the original sum be Rs. x.
Sum of the Ratios = 3 + 5 + 9 + 13 = 30

Therefore, C's share = \(\frac{9x}{30}=\frac{3x}{10}\)

A's Share = \(\frac{3x}{30}=\frac{x}{10}\)

According to the question,

\(= \frac{3x}{10} - \frac{x}{10} = 2412\)

\(x = 2412 \times 5 = \text{ Rs. 12060}\)

Thererfore, Amount received by B and D together
\(= \frac{ \left(5+13\right) }{30} \times 12060\)

= Rs.7236

Let the present age of Seema and Naresh be 5x and 7x years respectively.
According to the question,

\(\frac{5x+5}{7x+5}=\frac{3}{4}\)

=> 21x + 15 = 20x + 20
=> x = 20 - 15 = 5

Therefore, Naresh's present age

= 7x years = 7×5 = 35 years

A3 : 3 : 10

B23 : 33 : 60

C10 : ll : 20

DCant be determined

Nithin ? undefined

Correct answer is: 23 : 33 : 60

Explanation:

Simplest way to understand.

15% increment in A Salary, So,
2*15% = 0.3.

Total Salary of A after increment = 2+0.3 = 2.3.

10% increment in B Salary, So,
3*10% = 0.3.

Total Salary of B after increment = 3+0.3 = 3.3.

20% Increment in C Salary, So,
5*20% = 1.

Total Salary of C after increment = 5+1 = 6.

Ratio of salary of A, B & C after increment.

2.3 : 3.3 : 6.0.

So 23 : 33 : 60 is answer

ARs.26,000

DData inadequate

Nithin ? undefined

Correct answer is: Data inadequate

Explanation:

Let the earnings of A and B be Rs.4x and 7x respectively.
After 50% increase. A's earnings = 150% of 4x
After 25% decrease, B's earning = 75% of 7x
Ratio = 150% of 4x : 75% of 7x = 8 : 7
But their total earnings are unknown.
Hence A's earnings can't be known.
