Box A contains one 100 g block, one 20 g block and three 5 g blocks. Box B contains one 50 g block and three 10 g blocks. Jasmine moves some of the blocks from Box A to Box B and some of the blocks from Box B to Box A. After these moves, Box A contains 65 g less than it originally did and Box B contains 65 g more. What is the fewest number of blocks that Jasmine could have moved from Box A to Box B?

Answer: 2 boxes

Explanation:

A=Box A. a=A-65. B=Box B. b=B+65

A=100+20+5

A=125

A-65=125-65

a=60

B=50+10+10+10

B=80

B+65=80+65

b=145

b=A+20

a=B-20

b=100+20+5+10+10 ==> Change in +2 boxes

a=50+10 ==> Change in -2 boxes
