Answer:
72 years
Step-by-step explanation:
Let Drake's age be D years .
It's given that Celine's age is 4 years greater than 1/3 of drake's age .
1/3 of Drake's age = [tex]\frac{D}{3}[/tex]
So, Celine's age = [tex]\frac{D}{3}+4[/tex] ....(i)
It's given that celine is 28 years old .....(ii)
On equating equations (i) and (ii) , we get
[tex]\frac{D}{3}+4=28[/tex]
{ Transposition : Transposition means to take one number to the other side by changing it's operation }
On transposing 4 to RHS ,we get
[tex]\frac{D}{3}=28-4=24[/tex]
On transposing 3 to RHS ,we get
[tex]D=24[/tex]× 3 = 72
So, Drake is 72 years old .
