Question

Bianca is four times older as her sister. Three years from now, she will be ten years more than thrice the age of her sister. What is bianca’s present age?

Answer 1

Let present age of sister be x
So present age of Bianca will be 4x
Age of sister after 3 years will be (x+3)
And Bianca’s age after 3 years will be 10+3(x+3)

So,
4x + 3 = 10 + 3( x+3)
4x + 3 = 10 + 3x + 9
4x - 3x = 19 - 3
x = 16 years
Bianca’s present age = 4*16 = 64

Answer 2

64 years
