Garima. Find Sudha's present age.​

Answer 1

Answer:

Sudha = 40 years

Carima = 20 years

Step-by-step explanation:

Given:

• Sudha is twice as old as carima
• 10 years ago sudha was three times as old as carima

To find:

• Present age of Sudha

According to the question:

Let age of Sudha be X and age of Carima be Y

Substituting the values:

• X=2Y ------(1)

Now going for second condition:

(X-10)=3(Y-10)

X-10=3Y-30

X=3Y-30+10

X=3Y-20----(2)

Substituting the value of X from equation 2 in equation 1 :

3Y-20=2Y

3Y=2Y+20

3Y-2Y=20

Y=20

X=2×20

X=40 years

The age of Sudha is 40 years and the value of age Carima is 20 years
