Question

meena and teena's ages are in the ratio 3:7. if teena is 21 yrs old, what is meena's age?

Answer 1

Answer:

9 years

let,

meena = 3x----eq1

Teena = 7x------eq2

given that,

Teena = 21 years.

So, from eq2

7x=21

x= 3

Therefore,

substituting value of x in eq1

=>3x

=>3×3

=>9 years
