Question

3) After 9 years, the sum of the ages of Rina and Miza will be 90. If
Rina is 6 years younger than Miza today, then find the sum of
present ages of Rina and Miza.​

Answer 1

Answer:

Let Reena's present age be x years

⇒ Ajay's present age=x−6

and x+x−6=28

⇒2x=34

⇒x=17

⇒ Reena's age=17,

Ajay's age=11.

Answer 2

Step-by-step explanation:

let the age of miza be x

and the age of Reena be x-6

after 9 years

x+9 +( x-6)+9= 90

x+x-6+9+9= 90

2x+18-6 = 90

2x +12= 90

2x= 90-12

2x= 78

x = 78/2

x= 39

The age of Miza is 39 and the age of Reena is 33

After 9 years,

The age of Miza is 48 years and the age of Reena is 42 years.
