Question

Ten years ago,A's age was half of B's age . If the ratio of their ages is 3:4 , what will be the sum of their present ages.

Answer 1

Answer:

35

Step-by-step explanation:

Let A's age is 3x & B's age is 4x.

According to the question,

3x-10 = (4x-10)/2

=)2(3x-10)=4x-10

=)6x-20=4x-10

=)6x-4x=20-10

=)2x=10

=)x=5

Sum of their present ages=3x+4x=7x=7×5=35
