Solution:
Cost price of Dishwasher bought by Noel Divine = $ 320
Down payment = $ 20
Amount given in one installment= $ 34
Total Amount paid in 10 Installment = $34 ×10=$ 340
Total amount paid for Dishwasher by Noel Divine = $340 + $ 20 = $ 360
Interest paid by noel = $ 360 - $ 320= $ 40
As the interest will be simple interest
Simple interest =[tex]\frac{Principal \times \text{time} \ \text{rate}}{100}[/tex]
40=[tex]\frac{320 \times R \times \frac{10}{12}}{100}[/tex]
R= [tex]\frac{48000}{3200}[/tex]=15% →→Option A
