Question

the ratio of the age of maya and riya is 5:6 if the age of riya be 18 yrs find the age of maya​

Answer 1

Answer:

15 years

Step-by-step explanation:

Method I -

Ratio of their ages = 5:6 (1)

As age of riya is 18, multiply (1) by 3 [ so as to make right side 18 ]

= 5×3 : 6×3 = 15:18

Hence age of Maya is 15 years

Method II -

Let the age of Maya be 5x and age of Ria be 6x where 'x' is their common factor.

ATQ,

6x = 18 years

=> x = 18/6 = 3

So the age of maya = 5x = 5 × 3 = 15 years

Answer 2

Answer:

Maya's age is found to be 15 years.

Step-by-step explanation:

We have been given here that the ratio of the given ages of two girls, Maya and Riya are 5: 6 . It is also given above that the age of Riya is 18 years.

Let us assume that the age of Maya is m years. Therefore we have,

$\frac{5}{6} = \frac{m}{18}$

⇒ m  = $\frac{5}{6}$ × 18

⇒ m = 5 × 3

⇒ m = 15

Therefore the age of Maya is 15 years.
