Question

The age of Geetha added to nine times the age of Seetha 55. six times the age of Geetha added to elleven times the age of seetha gives 115.What is the age of Geetha? What is the age of Seetha?​

Answer 1

Answer:

10 years and 5 years

Step-by-step explanation:

Let age of Geetha and Seetha be x and y years respectively.

According to question,

x + 9y = 55 ..... (i)

6x + 11y = 115 .....(ii)

Multiplying equation (i) by 6 and subtracting equation (ii) from it

6(i) - (ii)

=> 43y = 215

=> y= 5

using y = 5 in equation (i)

x + 9(5) = 55

=> x = 55-45

x = 10

Thus age of Geetha is 10 years and age of Seetha is 5 years.
