Question

The average age of three girls is 24 years if thier ages are in the ratio of 5:6:7.find the age of the youngest girl​

Answer 1

HELLO MATE

ANSWER:-

5* 24 = age of three girls = 120

We have,

5 + 6 + 7 = 24

or 120 / 24 = 5 which is a multiplier of factors

therefore, the age of youngest girl is 5*5 = 25 yrs

Answer 2

Answer:

Let 5x, 6x and 7x be the ages of the three girls.

A/Q,

Average age =24

=>(5x+6x+7x)/2 =24

=>18x/2 =24

=>x =(24*2)/18

=>x =24/9

=>x =8/3

So,

5x= 5*8/3

= 40/3

6x= 6*8/3

= 48/3

7x= 7*8/3

= 56/3

.·. The youngest age is 40/3.
