There were some guavas in 3 bags, L, M and N. 25% of the number of guavas in Bag L was equal to 10% of the number of guavas in Bag M. The number of guavas in Bag N was 70% of the total number of guavas. After Archie removed 25% of the guavas in Bag N, there were 870 more guavas in Bag N than in Bag M. In the end, how many guavas should be transferred from Bag M to Bag N so that the number of guavas in Bag L would be the same as Bag M?

Bag L : Bag M

710The total number of guavas in Bag L and Bag M is the combined repeated identity. Make the total number of guavas in Box L and Bag M the same. LCM of 7 and 3 = 21
Number of guavas removed from Bag N
=
25100 x 49 u
= 12.25 u
Number of guavas left in Bag N
= 49 u - 12.25 u
= 36.75 u
Number of more guavas in Bag N than Bag M
= 36.75 u - 15 u
= 21.75 u
21.75 u = 870
1 u = 870 ÷ 21.75 = 40

Number of guavas to be transferred from Bag M to Bag N so that the number of guavas in Bag L would be the same as Bag M.
= 15 u - 6 u
= 9 u
= 9 x 40
= 360
Answer(s): 360
