The product of a Aruna’s age 4 yr ago and 6 yr after is 200. Her age at both times being given in years. Find her present age

a. 16 yr
b. 24 yr
c. 14 yr
d. 21 yr


Let present age = x
age 4 years before = x-4
age 6 years after =x+6
product of ages = (x-4)(x+6)=200
=x² +2x-24=200
= (x+16)(x-14)=0]
x=-16 or 14
since age will not be negative, x=14
present age =14
