Question

the ratio between the present ages of a and b is 3:5 respectively.if the difference between b's present age and a's age after 4 years is 2,what is the total of the a's and b's present age​

Answer 1

Answer:

16 yrs

Step-by-step explanation:

Let the ages of A and B be 3x and 5x respectively.

According to the problem,

difference between the ages of A and B = 4

thus, 5x-3x=4

=>2x=4

=>x=4/2

=>x=2

Therefore,

A's age=3x=3×2

=6 yrs

B's age=5x=5×2

=10yrs

Total of A's and B's present age =( 10+6)

=16 yrs
