Step-by-step explanation:
Let the present age of anu be x years
Present age of bindu=x-7
As per condition
x(x+7)+2=200
x²+7x+2=200
x²+7x=200-2
x²+7x=198
x²+7x-198=0
x²+18x-11x-198=0
x(x+18)-11(x+18)
x-11=0. x+18=0
x=11. x= -18
As age cannot be naegative
Therefore, x= -18 is not applicable
x=11 years
Therefore, present age of anu =11 years
Present age of bindu =x-7
=4 years
Present age of anu =11 years
Present age of bindu =4 years
