Question

Deepak is twice as old as his brother Vikas. IF the difference of their age be 11 years find their present age answer with solutions

Answer 1

Deepak is x
vikas is y

x>y
$x = 2y \\ x - 2y = 0.....1$
$x - y = 11....2$

subtracting 1 from 2
$x - 2y = 0 \\ - (x - y = 11) \\ - x +y = - 11 \\ - y = - 11 \\ y = 11$
substitute y =11 In 2
$x - 11 = 11 \\ x = 11 + 11 \\ x = 22$
Therefore
vikas age Is 22 years
Deepak age is 11 years
