Question

after 5 years, the sum of the ages of reema and neha will be 30. if reem is 4 years younger than neha today, then find the sum of the present pages of reena and neha?​

Answer 1

Solution :-

Given that :-

Sum of ages of Reema and Neha after 5 years = 30

Reema is Four years younger than Neha.

Then

Let age of Reema be "x" years old then

Age of Neha = x + 4

Then age after five years

Of Reema = x + 5

Of Neha = (x + 4) + 5

= x + 9

Now as sum of ages after 5 years = 30

→ (x + 5) + (x + 9) = 30

→ 2x + 14 = 30

→ 2x = 16

→ x = 8

Then we have got the age of

Reema = 8 years

Neha = (8 + 4)

= 12 years

Now the sum of present ages

= 8 + 12

= 20

Answer 2

Answer:

The sum of Ages of Neha and Reema is 20 years.

Step-by-step explanation:

This question can be solved by making it in quadratic form.

So, let the age of Neha be x.

And the age of Reema will be x-4.

Now, after 5 years,

The age of Neha will be x+5

And the age of Reema will become x-4+5=x+1.

So, according to the question

After 5 years the sum of their ages would be 30.

So, A.T.Q.

$(x+5)+(x+1)=30\\2x+6=30\\2x=30-6\\2x=24\\ \therefore\ x=12$

So the present age of Neha is 12. And the age of Reema is (12-4)=8.

Now we need to find the sum of their present ages which is (12+8)=20
