Adam o na le $100 mme o batla go e dirisa go bula lefelo la go rekisetsa matlapa. A ka kgona go reka letlapa le le lengwe le le lengwe ka $5 mme a bo a rekisa le le lengwe le le lengwe ka $7. Fa a dirisa madi a gagwe otlhe mo kgwebong ya gagwe ya matlapa mme a rekisa 60% fela ya matlapa a gagwe, o latlhegelwa ke bokae?

The ratio of men to women on a bus is 5:9. If the total number of passengers on the bus is 84, and 20 women alight from the bus at the next stop, how many women have remained on the bus?
A ka kgona go reka matlapa a le 20 ka gonne 100 / 5 = <<100/5=20>>20
O rekisa matlapa a le 12 ka gonne 20 x .6 = <<20*.6=12>>12
O bona $84 ka go a rekisa ka gonne 12 x 7 = <<12*7=84>>84
O latlhegetswe ke $16 mo kgwebong ya gagwe ka gonne 100 - 84 = <<100-84=16>>16

The total ratio representing the number of women on the bus is 5+9=<<5+9=14>>14
The fraction from the ratio representing the number of women is 9/14, and since the total number of passengers representing the full ratio is 84, there are 9/14*84=<<9/14*84=54>>54 women on the bus.
If 20 women alight from the bus at the next stop, the number of women remaining on the bus becomes 54-20=<<54-20=34>>34
