Question

1. Vidhi is 10 years elder than Tithi. Tith
is 2 years younger than Swati but l ves
elder than Ekta. Their ages add up to
number which is a multiple of 3 between
121 to 125. Find the present age of each​

Answer 1

Answer:

Age of Ekta = 28.5 years

Age of Swati = 29.5 years

Age of Tithi = 27.5 years

Age of Vidhi = 37.5 years

Step-by-step explanation:

Let the age of Ekta be x years

Then, according to the question

Age of Swati = x + 1 years

Age of Tithi = x + 1 -2 = x - 1 years

Age of Vidhi = x - 1 + 10 = x + 9

The sum of the ages of Vidhi, Tithi, Swati and Ekta

= x + 9 + x - 1 + x + 1 + x

= 4x + 9

Number which is multiple of 3 bwteen 121 to 125 is 123

Thus

4x + 9 = 123

or, 4x = 114

or, x = 28.5

Thus age of Ekta = 28.5 years

Age of Swati = 29.5 years

Age of Tithi = 27.5 years

Age of Vidhi = 37.5 years

Answer 2

Answer:

Step-by-step explanation:

Let the age of Ekta be x years

Then, according to the question

Age of Swati = x + 1 years

Age of Tithi = x + 1 -2 = x - 1 years

Age of Vidhi = x - 1 + 10 = x + 9

The sum of the ages of Vidhi, Tithi, Swati and Ekta

= x + 9 + x - 1 + x + 1 + x

= 4x + 9

Number which is multiple of 3 bwteen 121 to 125 is 123

Thus

4x + 9 = 123

or, 4x = 114

or, x = 28.5

Thus age of Ekta = 28.5 years

Age of Swati = 29.5 years

Age of Tithi = 27.5 years

Age of Vidhi = 37.5 years
