Answer:
let the present age of ritu be x
if ritu were five years younger, then: x-5
then her age would be-
(x-5)² = 11+5x
x²-10x+25 = 11+5x
x²-10x-5x+25-11=0
x²-15x+14=0
x²-14x-x+14=0
x(x-14) -1(x-14) =0
(x-1) (x-14) =0
Step-by-step explanation:
so, the present age of ritu could not be 1 as 5 years ago her age would be negative. so her present age is 14.
I hope u understand the answer.

Step-by-step explanation:
present age=x
if she was 5 yrs younger her age would be x-5
According to question equation formed is
[tex](x-5)^{2}=11+5x[/tex]
[tex]x^{2} + 25-10x=11+5x\\ x^{2} +25-10x=11+5x\\x^{2} -15x+14=0\\x^{2} -14x-x+14=0\\x(x-14)-1(x-14)=0\\(x-1)(x-14)= 0\\x=14 or x=1[/tex]
x=1 isn't possible hence ritu's present age is 14
