Let Lakshmi age be (x) year, then 4 times of Lakshmi age be (4x).
therefore, Lakshmi father age is equals to 3 x + 4, but Lakshmi 's father is 49 years
therefore , we get the equation 3 x + 4 = 49
To solve this equation, transposing 4 from LHS to RHS , we get 3x =49 - 4 = 3x + 45
On dividing both sides by 3, we get = 15
HENCE, Lakshmi 's age is 15 years
