Answer:
240 trees
Step-by-step explanation:
Let the fraction of total no. of trees be 1.
Fraction of no. of mango trees =1/5
Fraction of No. of litchi trees = 1/8
Fraction of No. of banana trees = 1/12
Fraction of No. of guava trees =1- 1/5 + 1/8 + 1/12
(LCM of 5 , 8, 12 = 120)
=1-( 24 + 15+ 10)/120
= 1 - 49 / 120
= (120 - 49)/120
= 71/ 120
Let the total total no. of trees be x.
No. of guava trees = 142
71/120 *x = 142
x = 142*120/71
x =240
Ans.=The total number of trees are 240.
