### Instruction:
 Padma anafanya biashara ya kubadilishana kadi na Robert. Padma alianza na kadi 75 na akabadilisha 2 za thamani yake kwa kadi 10 za Robert. Robert alianza na kadi 88 zake na akabadilisha kadi 8 zaidi kwa kadi 15 za Padma. Kadi ngapi zilibadilishwa kati ya Padma na Robert?


### Response:
 Kati ya Padma na Robert, kulikuwa na kadi 75 + 88 = <<75+88=163>>163 za kuanza.
Padma alibadilisha kadi 2 + 15 za kwake = <<2+15=17>>17 kadi.
Robert alibadilisha kadi 10 + 8 za kwake = <<10+8=18>>18 kadi.
Jumla ya kadi zilizobadilishwa kati yao ni 17 + 18 = <<17+18=35>>35 kadi.
