Question

Ram's and Hari's ages are in the ratio 12:7.3 years ago, their age ratio were 11:6. What was Hari's age 5
years ago?
​

Answer 1

Let Ram be= 12x
Let Hari be= 7x

3 years ago,
12x-3/7x-3= 11/6
6(12x-3)= 11(7x-3)
72x-18=77x-33
-18+33=77x- 72x
15= 5x
5x= 15
x= 15/5= 3
Hari was 3 years old.

Answer 2

Answer:

Hari's age 5 years ago = 16 years

Step-by-step explanation:

Given data

The ratio of the ages of Ram and Hari = 12:7

   3 years before the ratio = 11:6  

here we need to find Hari's age 5 years ago

Let 12x and  7x be the ages of Ram and Hari

⇒ before 3 years ages are

   Ram's age = 12x - 3

   Hari's age =  7x  - 3

then their ratio will be equals to 11:6

      ⇒     12x-3 : 7x -3 = 11:6

      ⇒    $\frac{ 12x - 3}{7x - 3 } = \frac{11}{6}$

      ⇒    6 (12x-3) = 11 (7x-3)

      ⇒    72x - 18 = 77x -33

      ⇒    77x - 72x   = 33 - 18

      ⇒    5x = 15

      ⇒    x = 3

⇒ Hari's age = 7(3) = 21

⇒ Hari's age 5 years ago = 21-5 = 16 years
