Question

In a Orchard 1/5 are orange trees 3/13 are mango trees and the rest are banana trees.If the banana trees are 148 in number find the total number of trees in the Orchard

Answer 1

Let the total no. of trees be x

A/Q

x = x/5 + 3x/13 + 148

Taking LCM = 65

x \:  =  \frac{13x + 15x + 9620}{65}  

65x = 28x + 9620

65x - 28x = 960

37x = 9620

x = 260

Hence, there are 260 trees in orchard.
