Question

Present age of sunita is 3 times the presenf age of nita 4 years hence twice the age of sunita will equal to thrice the age of nita find the present age of sunita

Answer 1

Let Nita's present age be x years. Therefore sunita's present age is y years. y = 3x 4 years hence, Nita's age = (x+4) years Sunita's age = (y+4) years According to the question, 2(y+4) = 3(x+4)    {substituting y=3x} 2(3x+4)=3x+12 6x-3x+8-12=0 3x-4 = 0 x = 4/3 Therefore sunita's present age = y = 3x = 3 x 4/3 = 4 years.
