There were some mangoes in 3 bags, X, Y and Z. 20% of the number of mangoes in Bag X was equal to 10% of the number of mangoes in Bag Y. The number of mangoes in Bag Z was 60% of the total number of mangoes. After John removed 25% of the mangoes in Bag Z, there were 110 more mangoes in Bag Z than in Bag Y. In the end, how many mangoes should be transferred from Bag Y to Bag Z so that the number of mangoes in Bag X would be the same as Bag Y?

35The total number of mangoes in Bag X and Bag Y is the combined repeated identity. Make the total number of mangoes in Box X and Bag Y the same. LCM of 3 and 2 = 6
Number of mangoes removed from Bag Z
=
25100 x 9 u
= 2.25 u
Number of mangoes left in Bag Z
= 9 u - 2.25 u
= 6.75 u
Number of more mangoes in Bag Z than Bag Y
= 6.75 u - 4 u
= 2.75 u
2.75 u = 110
1 u = 110 ÷ 2.75 = 40

Number of mangoes to be transferred from Bag Y to Bag Z so that the number of mangoes in Bag X would be the same as Bag Y.
= 4 u - 2 u
= 2 u
= 2 x 40
= 80
Answer(s): 80
