Question

sum of the ages of Monali and Sonali is 29 yrs . Monali is younger than Sonali by 3 yrs . Find their ages (solve graphically)​

Answer 1

Answer:

Age of Sonali is 13 yr and that of Monali is 16 yr

Step-by-step explanation:

Let's assume that age of Monali  is x and that of sonali is y

According to 1st condition

• sum of the ages of Monali and Sonali is 29 yrs
• x + y = 29

According to second Condition

• Monali is younger than Sonali by 3 yrs
• x = y + 3

Substitue x = y + 3 in equation x + y  = 29

• y +3 +y =29
• 2y = 26
• y = 13 yr

Now

• x = y +3
• x = 13 +3
• x = 16 yr
