Answer 1

Answer:

15

Step-by-step explanation:

Hey!!!

____________________________

●Let the age of Sahil and Nikhil be 4x and 3x

After 5 years,

Age of Sahil and and Nikhil =4x+5 and 3x +5

ATQ

\frac{4x + 5}{3x + 5} = \frac{5}{4}

3x+5

4x+5

=

4

5

By cross multiplication

4(4x+5)=5(3x+5)

16x+20=15x+25

16x-15x=25-20

x=5

Hence,Present age of Sahil=4x=4×5=20

And,present age of Nikhil=3x=3×5=15

Answer 2

Given:

Ratio of Sahil's and Nikhil's age

To find:

Their present age

Solution:

Let the age of Sahil be= 4x

Ler the age of Nikhil be= 3x

$after \: 5 \: years$

Sahil's age= 4x+5

Nikhil's age= 3x+5

$4x + 5 \div 3x + 5 = 5 \div 4$

$4(4x + 5) = 5(3x + 5)$

$16x + 20 = 15x + 25$

$16x - 15x = 25 - 20$

$x = 5$

Sahil's age= 4×5= 20 years

Nikhil's age= 3×5= 15 years
