Question

2 years ago, the addition of ages of father-mother and their two daughters was $40$ years. After 3 years the addition of their ages will be ..............

• A. $40$
• B. $46$
• C. $50$
• D. $60$

Answer 1

Answer: (D)

$60$

The sum of the ages of father-mother and their two daughters $=40$ before 2 years.
Hence at present i.e., after two years the age of all $4$ members will increase by $2$ for each member.
$\therefore$ Sum of their ages at present $=40+2+2+2+2=48$
After $3$ years from the present time, each of the member's age will increase by $3$
$\therefore$ Sum of their ages after $3$ years $=48+3+3+3=60$

Hence, the answer is $60$.
