Question

banu is 20 years older than binu.in 5 years banu will be twice as old as binu. find their present ages​

Answer 1

solved by using linear equation

Answer 2

Answer:

Step-by-step explanation:

let binu's age = x years

banu's age = x + 20 years

in 5 years

binu's age = x + 5 years

banu's age = x+ 20 + 5

therefore,

x + 25 = 2(x+5)

x + 25 = 2x + 10

x = 15 years

binu = 15 years

banu = 35 years
