Expert Solution

Step 1
here we are using trail and error method to find the solution
if we consider option A
if jenny picks 42 apples
she has to give 1/4 of 42 apples to jerome
it is not possible because 42 is not divisible by 4
if we consider option B
if jenny picks 70 apples
she has to give 1/4 of 42 apples to jerome
it is not possible because 70 is not divisible by 4
similarlly
from option C,D,E
45,58,74 are not divisible by 4
so options A,B,C,D,E, are not correct answers
Step by step
Solved in 2 steps
