The ratio of the present age of Meena and Fiona is 16 : 13 respectively. Four years ago the respective ratio of their age was 14 : 11. What will be Fiona's age four years from now?

A8 years

B32 years

C26 years

DNone of these

Nithin ? Aug 15 '2022 at 8:38

Correct answer is: None of these

Explanation:

Let the present age of Meena and Fiona be 16x and 13xyears respectively.
According to the question,

\(\implies \Large \frac{16x-4}{13x-4}=\frac{14}{11}\)

\(\implies 176x - 44 = 182x - 56\)

\(\implies 182x - 176x = 56 - 44\)

\(\implies 6x =12 => x = \frac{12}{6} = 2\)

Therefore, Fiona's age after four years = 13x + 4

\(= 13×2+4 = 30 \text{ years}\)

Radha's present age is three years less than twice her age 12 years ago. Also the respective ratio between Raj's present age and Radha's present age is 4 : 9. What will be Raj's age after 5 years?

A12 years

B7 years

C21 years

DNone of these

Nithin ? Aug 15 '2022 at 8:24

Correct answer is: None of these

Explanation:

Let Radha's present age = x years.

Therefore, \(x = 2 \left(x-12\right)-3\)

\(\implies x = 2x - 24 - 3 \implies x = 27\)

Therefore, Raj's present age = \(\Large \frac{4}{9} \times 27\) = 12 years

Therefore, Raj's age after 5 years = 12 + 5 = 17 years

The ratio between the age of a father and a son at present is 5 : 2 respectively. Four years hence the ratio between the age of the son and his mother will be 1 : 2 respectively. What is the ratio between the present age of the father and the mother respectively?

A3 : 4

B5 : 4

C4 : 3

DCannot be determined

Nithin ? Aug 15 '2022 at 7:37

Correct answer is: Cannot be determined

Explanation:

Let the present age of father and son be 5x and 2x years respectively.

After 4 years,

and mother's age = 2y years

Now, y = 2x + 4 => x = \(\Large \frac{y-4}{2}\)

Therefore, Father's present age = \(\Large 5\frac{ \left(y-4\right) }{2}\) years

 

Mother's present age = (2y - 4) years

Clearly, data are inadequate.

The present age of Vishal and Shekhar are in the ratio of 14 : 17 respectively. Six years from now, their age will be in the ratio of 17 : 20 respectively. What is Shekhar's present age?

A7 years

B51 years

C34 years

D28 years

Nithin ? Aug 14 '2022 at 21:31

Correct answer is: 34 years

Explanation:

Let the present age of Vishal and Shekhar be14x and 17x years respectively.

After 6 years,
\(\Large \frac{14x+6}{17x+6}=\frac{17}{20}\)

\(\implies 280x + 120\)

\(\implies 289x + 102 = 9x = 18\)

\(\implies x = \frac{18}{9} = 2\)

Shekar's present age

\(=\Large 17 \times 2\)

= 34 years

A25 years

B20 years

C30 years

D24 years

Nithin ? Aug 14 '2022 at 21:22

Correct answer is: 20 years

Explanation:

Let the present age of Tina and Rakesh be 9x and 10x years respectively.

10 years ago.

\(=\Large \frac{9x-10}{10x-10}=\frac{4}{5}\)

\(\implies 45x - 50 = 40x - 40\)

\(\implies 5x = 10 \implies x = \frac{10}{5} = 2\)

Therefore, Rakesh's present age = 10x

\(=\Large 10 \times 2 = 20 \text{ years}\)

Four years ago, Shyam's age was 3/4 times of that of Ram. Four year hence, Shyam's age will be 5/6 times that of Ram. What is the present age of Shyam?

A15 yr

B20 yr

C16 yr

D24 yr

Nithin ? Aug 14 '2022 at 21:12

Correct answer: 16 yr

Explanation:

4 yr ago, let Ram's age = x yr and Shyam's age = \(\frac{3}{4}x\) yr

 

Now, Ram's present age = (x + 4) yr and Shyam's present age = (\(\frac{3}{4}x\)+4) yr
According to the question,
\(\large\frac{5}{6}(x + 4 + 4) = \left(\frac{3}{4}x + 4 + 4\right)\)

4 (5x + 40) = 6(3x + 32)

20x + 160 = 18x + 192

2x = 32

x = 16

Hence, present age of Shyam

\(= \large\frac{3}{4}\times 16 + 4\)

\(=16 \text{ yr}\)

A 40 yr

B45 yr

C30 yr

D35 yr

Nithin ? Aug 14 '2022 at 21:1

Correct answer is: 35 yr

Explanation:

Suppose the present age of Amit and his father is 2x and 5x respectively.
After 4 years the ratio of their ages,

(2x+4):(5x+4)= 5:11
\(25x + 20 = 22x+44\)

\(25x-22x=44-20\)

\(3x=24\)

\(x=8\)

Age of his father before 5 years

\(=5x-5\)

\(=5 \times 8 -5\)

\(= 40 - 5\)

= 35 yr
