  1. Step-by-step explanation:

    Let the cost of radio be “x”.

    Principal = P = 500

    Rate = R = 5% per annum

    Time = T = 3 years

    Amount (Money he returned back) = Simple Interest + Principal = SI + P = Rs 350 + Cost of Radio

    Now,

    [tex]si \: = \frac{p \times r \times t}{100} \\ = \frac{rs \: 500 \times 6 \times 3}{100} \\ = rs \: 5 \times 6 \times 3 = rs \: 90[/tex]

    So, Simple Interest = Rs 90

    Amount = SI + P = Rs 500 + Rs 90 = Rs 590

    Amount = Cost of Radio + Rs 350

    Rs 590 = Cost of Radio + Rs 350 (By Transposition)

    Cost of Radio = Rs 590 – Rs 350 = Rs 240

    Hence, cost of radio is Rs 240.

    Formula Used :

    [tex]SI = \frac{PRT}{100} [/tex]
