Answer:
Sum of ages = 25
Let friend's ages be x
Bina = x + 1
⇒ x + x + 1 = 25
2x + 1 = 25
2x = 25 - 1 = 24
2x = 24
x = 24
2
x = 12
Bina's friend's age = 12
Bina's age = 12 + 1 = 13

Answer:
bina's age =13 years
friends age=12 years
Step-by-step explanation:
let her friend's age be x,
then Bina's age be (x+1)
according to the question:
x+(x+1)=25
=>2x+1=25 years
2x=25-1= 24 years
x=24/2=12
therefore, bina's age is x+1 i.e. 12+1 =13 years
thanks
hope helps
