Question

Sandy's age is 5 more than thrice radha's age.lf the sum of their ages is 65,find sandy's age and radha's age. (Write the equations and solve it,)

Answer 1

Sandy's age= 3y+5
Radha's age= y

y+(3y+5)=65
4y+5=65
4y=60
y=15

Answer 2

 radha's age= x 
sandy's age = 3x+5
sum of their ages = 65
x+3x+5=65
4x+5 = 65
4x= 65-5
4x=60
x=60/4
x=15
radha's age = 15
sandy's age= 15*3+5 
                     =50
