Answer 2

To Find:-

• Find their present ages.

Given:-

• Ojal's mother is thrice as old as Ojal.
• After 12 years, her age will be twice that of her daughter.

Solution:-

Let Ojals age be " x "

Then mother age be " 3x "

After 12 years, her age will be twice that of her daughter.

So,

$\tt\implies \: 3x + 12 = 2( x + 12 )$

$\tt\implies \: 3x + 12 = 2x + 24$

$\tt\implies \: 3x - 2x = 24 - 12$

$\tt\implies \: x = 12 \: years$

Hence,

• $\tt \: Ojal's \: \: age \: \: is \: \: 12 \: \: years.$
• $\tt \: Mother's \: \: age \: \: is \: \: 3x = 3( 12 ) = 36 \: years$
