Question

veena is six year old than her brothe.if the sum of their ages is 28year. find their present age

Answer 1

Let's assume Veena is x years old then her brothers who's 6 years younger will be x-6.

Then,

x + (x-6) = 28 ....... that is the sum of their ages

2x-6=28

2x=22

x=11

So veena is 11 years old and her brother is x-6 = 11-6 = 5 years old.

Answer 2

let age of brother of veena is x years now age of veena is
y = (x+ 6) .....(1)
x+ y =28 ...(2)
pit value
of y in second equation
X + X + 6 , = 28
2x = 22
X = 11 years
age of veena is is 12 years
