Answer:
The age of the youngest mango sapling in her farm is 9 yrs.
Step-by-step explanation:
Let the age of youngest (4th) mango sapling be x yr.
As saplings are planted at an interval of 2 yrs.
The age of 3rd mango sapling =(x - 2)yrs.
The age of 2nd mango sapling = (x - 2 - 2) =(x - 4) yrs.
The age of 1st mango sapling = (x -6 ) yrs.
According to the question
x + (x -2 )+ (x - 4 )+( x - 6) = 24
4x - 12 = 24
4x = 24 +12
x =36 / 4 = 9 yrs.
