Answer 1

Answer:

Age of Cheenu = 25 years

Age of Charu = 14 years

Step-by-step explanation:

Cheenu is 11 years older than Charu

Three years ago Cheenu was twice as old as Charu

To find:

Present ages of Cheenu and Charu

Let the ages of Cheenu and Charu be X and Y respectively

According to the question:

X=11+Y ---(1)

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

X-3=2Y-6

X-3+6=2Y

X+3=2Y

SUbstituting the value of X from (1) in the above equation:

11+Y+3=2Y

14=Y

X = 11+14 = 25

Answer 2

$\huge\sf\pink{Answer}$

☞ Age of Cheenu = 25 years

☞ Age of Charu = 14 years

$\huge\sf\blue{Given}$

✭ Cheenu is 11 years older than Charu

✭ Three years ago Cheenu was twice as old as Charu

$\huge\sf\purple{Steps}$

$\large\underline{\underline{\sf Let}}$

◕ Cheenu's Age = x

◕ Charu's Age = y

☯ $\underline{\sf As \ Per \ the \ Question}$

➝ $\sf x = 11+y\:\:\: -eq(1)$

& also

➳ $\sf (x-3) = 2(y-3)$

➳ $\sf x-3 = 2y-6$

➳ $\sf x-3+6 = 2y$

➳ $\sf x+3 = 2y$

➳ $\sf x = 2y-3$

Substituting value of x in eq(1)

»» $\sf 2y-3 = 11+y$

»» $\sf 2y-y = 11+3$

»» $\sf \red{y = 14}$

Substituting the value of y in eq(1)

➠ $\sf x = 11+14$

➠ $\sf \orange{x = 25}$
