Question

age is 5 times as that of B 10 years later age will be thrice that we find as
​

Answer 1

Step-by-step explanation:

a=5b

a+10 = 3 (b + 10) = 3b + 30

a= 3b + 20 = 5b

2b = 20

b = 10

a = 50

Answer 2

Answer:

Solution : Present age of B = x years

Present age of A = 5x years

According to question

5x + 10 =3(X+ 10)

5x + 10 = 3x + 30

5x – 3x = 30 – 10

2x = 20

X = 20/2

X = 10

Hence present age of B = 10 years

And present age of A =5x10 = 50 years
