neha's father is 4 times as old as neha.after 5 years,her father will be 3 times as old as she is.how old is Neha right now?​

Answer 1

Answer:

let,

neha age be x

then,beha's father age be 4x

after 5 year,

neha age x+5

his father age 4x+5

according to Question

3(x+5)=4x+5

3x+15=4x+5

3x-4x=5-15

-x=-10

x=10

so, her age =10year

her father age =4x=4×10=40year

Answer 2

Answer:

Neha is presently 10 years old.

Step-by-step explanation:

Given :

Neha's father = 4 times as old as neha is

5 years later = father will be 3 times as old as she is

To find :

Present age of Neha

Solution :

Let the Present ages be -

• Neha as x
• Father as 4x

$\rule{300}{1.5}$

Ages 5 years hence -

• Neha = (x + 5)
• Father = (4x + 5)

$\rule{300}{1.5}$

According to the Question -

5 years later = father will be 3 times as old as she is

➨ (4x + 5) = 3(x + 5)

➨ 4x + 5 = 3x + 15

➨ 4x - 3x = 15 - 5

➨ x = 10

Neha = 10 years

$\therefore$ Neha is presently 10 years old.
