Question 72

15 years ago Cynthia was thrice as old as Brittany. The sum of their present ages is 94 years. How old is Brittany now?

Solution

15 years ago , let the age of Cynthia be c and Brittany be b.

c = 3b

Present ages of Cynthia will be (c+15) and Brittany be (b+15). Their sum is 94.

c + 15 + b+ 15 = 94

=> c+b= 64

=> 4b = 64

=> b = 16

Present age of Brittany is 31 years (16 + 15).

So , the answer would be option d)31 years.
