did qn say no of blue beads is twice the red beads at first?

No, the bar for red beads was thicker than the blue beads one.

Just that their widths are the same, this will be easier for us to group them together to show (1 unit of red beads + 1 part of blue beads) is equal to 110 beads

Where can we find this type of qns?TIA
