<PRE><B>Question 998387</B>
There are 45 apples in carton A and 55 Apples in carton B
 how many apples must be transferred from carton B to carton A so that the number of apples in carton A is 3 times as many as the number of apples in carton B 
:\
let x = no. of apples required to be transferred
45 + x = 3(55 - x)
45 + x = 165 - 3x
x + 3x = 165 - 45
4x = 120
x = 120/4
x = 30 apples transferred
:
:
See if this checks out
45 + 30 = 3(55 - 30)
75 = 2(25)</PRE>
