Question

14 John lent Rs. 2550 to Mohan at 7.5 per cent per annum. If Mohan discarges the debt after 8 monthes by giving an old black and white television and Rs. 1422.50; find the price of the television.

Answer 1

P= Rs. 2550
R= 7.5 %
T= 8 months= \frac{8}{12} years
=\frac{2}{3} years
S.I.=$\frac{PTR}{100}$
$=Rs.2550\times 7.5\times \frac{2}{3}\times \frac{1}{100}$
$=Rs.\frac{2550\times 7.5\times 2}{3\times 100}$
$=Rs.\frac{2550\times 5}{100}$
$=Rs.\frac{12750}{100}$
=Rs. 127.50
Amount=P+I
=Rs. 2550 +Rs. 127.50
=Rs. 2677.50
Mohan paid in cash =Rs. 1422.50
Price of the television
=Amount - Paid in cash
=Rs. 2677.50-Rs. 1422.50
=Rs. 1255
