Question

The ages of A and B three years ago were ' x ' and 'y + 2 ' years , therefore the sum of their ages 4 years hence will be _______years

1 point

x + y - 12

x + y + 12

x + y + 16

x + y - 16



​

Answer 1

Step-by-step explanation:

A's age 3 years ago: x

so A's present age will be (x+3)

B's age 3 years ago is y+2

so B's present age will be (y+2+3)=(y+5)

A's age four years hence will be

A's present age+4years

(x+3)+4=(x+7)...................................(1)

B's age four years hence will be

B's present age+4years

(y+5)+4=(y+9)..................................(2)

Adding (1) and (2):

(x+7)+(y+9)

x+y+7+9

x+y+16

Therefore, the correct answer is: x+y+16

Answer 2

Answer:

x+y+16

Step-by-step explanation:

Age of A 3 yrs ago : x years

So, present age of A is : x+3 yrs

Age of B 3 years ago : y+2 years

So, present age of B is : y+5

Age of A 4 years hence(after) : x+3+4 =x+7

Age of B 4 years hence : y+5+4 = y+9

So, Sum of ages of A and B after 4 yrs : (x+7) + (y+9) = x+y+16

Hence, answer to this question is x+y+16
