1 `xx` `3/4` = `3/4`
7 `xx` `1/4` = `7/4` = 1`3/4`
1 `-:` `3/4` = 1`xx` `4/3` = 1`1/3`
`3/4` + `1/4` = `4/4` = 1
7 `xx` `1/4` is the correct answer.

Before-
P : S
3 : 8
After Simon replaced `3/4` of his marbles, he has `1/4` left
8u `xx` `1/4` = 2u
After-
P : S
3 : 2
Difference
3u - 2u = 1u
1u = 120 marbles
No. of marbles peter had
3u = 120 `xx` 3 = 360

Toatl weight of sugar
1`1/6` + `3/4` = 1`2/12` + `9/12` = 1`11/12` kg
No. of bags of sugar
1`11/12` `-:` `1/12` = `23/12` `xx` `12/1` = 23
