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

Present age of Seema and Naresh are in the respective ratio of 5:7. Five years hence the ratio of their age becomes 3 : 4 respectively. What is Naresh's present age (in years)?

A25

B40

C30

DNone of these

Nithin ? undefined

Correct answre is: None of these

Explanation:

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

Salaries of A, B and C are in the ratio of 2 : 3 : 5 respectively. If their salaries were increased by 15%, 10% and 20% respectively what will be the new respective ratio of their salaries?

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

BRs.28,000

CRs.21,000

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.

ARs.80 lakhs

BRs.50 lakhs

CRs.40 lakhs

DRs.60 lakhs

Nithin ? undefined

Correct answer is: Rs.40 lakhs

Explanation:

A : B = 5 : 8
Let A's income be 5x and B's income be 8x.
According to question.

\(\Large \frac{5x+25}{8x}=\frac{5}{4}\)

\(\frac{5 \left(x+5\right) }{4 \times 2x}=\frac{5}{4} => \frac{x+5}{2x} = 1\)

x + 5 = 2x
x = 5

\(\text{B's Income} = 8x = 8×5\)

= Rs.40 lakhs.

A14 : 5

B5 : 8

C13 : 4

DNone of these

Nithin ? undefined

Correct answer is: None of these

Explanation:

Ratio of no. boys : girls = 2 : 3
Let the no. of boys = 2x
Then the no. of girls = 3x
No. of boys after 20% increase = 1.20 x 2x = 2.4 x.
No. of girls after 10% increase = 1.10 x 3x = 3.3x
Required ratio

\(= \frac{2.4x}{3.3x}=\frac{8}{11} = 8 : 11\)

Correct answer is: Rs. 6400

Explanation:

Let P's share be 6x
Q's share be 19x and
R's share be 7x.
Total sum = 6x + 19x + 7x = 32x
6x : 19x + 200 : 7x - 200
= 3 : 10 : 3
We can write
6x = 7x - 200 => x = 200
Total sum = 32x = Rs.6400
