Buying the television of cash would cost Rs 7500.
Buying on hire purchase would cost :3000+(5*1000)=Rs8000
You realize that that the hire purchase price is higher by Rs 500
The percentage interest is therefore
500/7500*100%=6.67%
Thus rate=6.67%

Answer:
Annual Rate under the installment plan = 16%
Step-by-step explanation:
Cost Price of television = Rs. 7500
Cash which is to be paid at time of purchase = Rs. 3000
Installment to be paid each month = Rs. 1000
Cost Price of television Under installment plan = 3000 + 5 × 1000
= Rs. 8000
Interest Paid by the customer = 8000 - 7500
= Rs. 500
Time = 5 months
⇒ Time = 0.42 years ( 1 year = 12 months )
Principal = Rs. 7500
Simple Interest = Principal × Rate × Time
⇒ 500 = 7500 × Rate × 0.42
⇒ 500 = Rate × 3125
⇒ Rate = 0.16
⇒ Rate = 0.16 × 100 = 16% per annum
