### Instruction:
 Peter ana vitabu 20. Amesoma 40% yao. Ndugu yake amesoma 10% yao. Peter amesoma vitabu vingapi zaidi kuliko ndugu yake?


### Response:
 Peter amesoma vitabu 8 kati ya hivyo kwa sababu 20 x .4 = <<20*.4=8>>8
Ndugu yake amesoma vitabu 2 kati ya hivyo kwa sababu 20 x .1 = <<20*.1=2>>2
Peter amesoma vitabu 6 zaidi kuliko ndugu yake kwa sababu 8 - 2 = <<8-2=6>>6
