Answer 1

Answer:

Step-by-step explanation:

Let son be x

A.T.Q

4x=x

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

4x+5=4x+15

8x=10

x=10/8

x=0.8

4x=3.2

Answer 2

Answer :

Mr.Singh = 40 years old

Son = 10 years old

Explaination :

→ Consider the age of the son as x

→ Present situation =

→ Son = x

→ Mr. singh = 4x

5 years hence -

→ Son's age = x + 5

→ Singh 's age = 4x + 5

★ Equation = ★

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

=> 4x +5 = 3x + 15

=> 4x - 3x = 15 - 5

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{ x = 10 }}}}}}}$

So,

→ Mr. Singh's age = 4x

=> 4 × 10

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{ Mr.Singh=40\:years }}}}}}}$

→ Son's age = x

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{ Son=10\:years.}}}}}}}$

★ Lets check whether they meet the conditions ★

→ 5 years later =

→ Mr.singh = 45

→ Son = 15

★ It meets the condition that Mr.singh is 3 times of his son after 5 years. ★

∴ Present age of Mr.singh is 40 years.

∴ Present age of Son is 10 years.
