### Instruction:
 Siku ya kitaifa ya rujnu ya midomo, nusu ya wanafunzi waliohudhuria darasani walivalia rujnu ya rangi. Kati ya wanafunzi waliovalia rujnu, robo moja walivalia rujnu nyekundu. Kulikuwa na wanafunzi waliokuwa wamevalia rujnu ya bluu nusu ya idadi ya wanafunzi waliovalia rujnu nyekundu. Ikiwa wanafunzi 200 walihudhuria shule siku hiyo, wangapi walivalia rujnu ya bluu?


### Response:
 Kati ya wanafunzi waliohudhuria darasani, 1/2 walivalia rujnu ya rangi, na kati ya wale waliovalia rujnu, 1/4 walivalia rujnu nyekundu, hivyo 1/2*1/4=1/8 ya wanafunzi walivalia rujnu nyekundu.
Kwa kuwa kulikuwa na wanafunzi waliokuwa wamevalia rujnu ya bluu nusu ya idadi ya wanafunzi waliovalia rujnu nyekundu, basi 1/8*1/5=1/40 ya wanafunzi walivalia rujnu ya bluu.
Ikiwa wanafunzi 200 walihudhuria shule siku hiyo, basi 200*1/40=<<200*1/40=5>>5 wanafunzi walivalia rujnu ya bluu.
