Answer 1

$<b><u>$ hello♥️
Here is the solution..

Let the age of lalu be x
And the age of Leena be x + 3

Their ages after 4 years⤵️⤵️

Lalu ➡️( x) +4

Leena ➡️(x + 3) + 4

We know that after 4 years the sum of their ages will be 33.

So,

ACCORDING TO QUESTION :--

(X) +4 + ( x +3) + 4 = 33

2x +11 = 33

2x = 33 - 11

2x = 22

X = 22/2

X = 11

So, the age of lalu (x) is 11
And the age of Leena (x + 3) is 14.

Answer 2

ANSWER:

Let the age of Lalu be = x years

So,as given in Question that Leena is 3 years older than Lalu, So-

Age of Leena = x + 3 years

Four years later -

Age of Lalu = x + 4

Age of Leena = x + 3 + 4 = x + 7

So, According to the Question-

Sum of age of Leena and Lalu is 33 years -

Age of Lalu + Age of Leena = 33

(x + 4) + (x + 7) = 33

2x + 11 = 33

2x = 33-11

2x = 22

x = 22÷2

x = 11

So,

Age of Lalu = x = 11 years

Age of Leena = x + 3 = 11 + 3 = 14 years
