Question

Ten years ago, P was half of Q's age. If the ratio of their present ages is 3:43:4, what will be the total of their present ages?​

Answer 1

Answer:

35

step by step explaining

Let present age of P and Q be 3x and 4x respectively.

Ten years ago, P was half of Q's age

⇒(3x−10)=1/2(4x−10)

⇒6x−20=4x−10

⇒2x=10

⇒x=5

Total of their present ages

=3x+4x=7x

=7×5=35
