Question

10 years back neeru was 4 times older than rashmi after 10 years neeru will be two times older than the rashmi find their present ages

Answer 1

Let Neeru's present age =X years
And Rashmi's present age = Y years

Their ages 10 years ago are X-10 and Y-10.
According to the question X-10= (Y-10) *4
X-10 =4Y-40
X-4Y+30=0 ....... (1)

After 10 years, X+10= (Y+10)*2
X +10=2Y+20
X-2Y-10=0….....(2)

solve the equations 1 and 2,

Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Let rashmi be x years old 10 years ago

Neeru = 4x

Find their age now:

Rashmi = x + 10

Neeru = 4x + 10

Find their age 10 years later:

Rashmi = x + 10 + 10 = x + 20

Neeru = 4x + 10 + 10 = 4x + 20

Solve x:

4x + 20 = 2(x + 20)

4x + 20 = 2x + 40

4x - 2x = 40 - 20

2x = 20

x = 10

Find their current age:

Rashmi = x + 10 = 10 + 10 = 20

Neeru = 4x + 10 = 4(10) + 10 = 50

Answer: Rashmi is 20 years old and Neeru is 50 years old
