Question

five year ago Sunny was three times as old as Mini. 10 year later Sunny would be twice as old as Mini. how old are they now.​

Answer 1

Let , mini's age = x
sunny 's age = 3x

After 10 years ,
mini 's age = x+10
sunny 's age = 3x + 10

S = 2( M )
3x + 10 = 2( x+10 )
3x -2x = 20-10
x = 10

so,
Present age of mini is 10 years
Present age of sunny is 30 years .

Answer 2

Answer:

Let, mini's age = x

sunny 's age = 3x

After 10 years ,

mini 's age = x+10

sunny 's age = 3x + 10

S = 2( M )

3x + 10 = 2( x+10 )

3x -2x = 20-10

x = 10

so,

Present age of mini is 10 years

Present age of sunny is 30 years.
