Hili ni swali kuhusu riba rahisi (simple interest). Kutoka kwenye swali, tunapewa: • Kiasi cha mkopo (Principal, P) = Sh 120,000 • Kiwango cha riba (Rate, R) = 16% kwa mwaka (p.a.) • Muda (Time, T) = miaka 3 a) Tafuta riba aliyolipa Step 1: Tumia fomula ya riba rahisi. Fomula ya riba rahisi (I) ni: I = (P × R × T)/(100) Step 2: Badilisha thamani za P, R, na T kwenye fomula. I = (120,000 × 16 × 3)/(100) Step 3: Fanya hesabu. I = (5,760,000)/(100) I = 57,600 Riba aliyolipa ni: Sh 57,600 b) Tafuta jumla ya kiasi alicholipa Step 4: Tumia fomula ya jumla ya kiasi. Jumla ya kiasi (A) alicholipa ni jumla ya kiasi cha mkopo na riba: A = P + I Step 5: Badilisha thamani za P na I kwenye fomula. A = 120,000 + 57,600 A = 177,600 Jumla ya kiasi alicholipa ni: Sh 177,600 Drop the next question.
