Show Answer

Answer:

Correct Answer: C

Solution:

Given, A = Rs. 956, P = 800 and r = 3yr $ SI=A-P=956-800=Rs.156 $

$ \therefore $ $ Rate=\frac{SI\times 100}{Principal\times Time}=\frac{156\times 100}{800\times 3} $ = 6.5% per annum

$ \therefore $ New rate = Old rate + 4% = 6.5%+ 4% = 10.5% Now, $ SI=\frac{\text{Principal }\times\text{ Time }\times\text{ Rate}}{100} $ $ =\frac{800\times 3\times 10.5}{100}=Rs\text{. 252} $

$ \therefore $ Amount $ =800+252=Rs\text{. 1052} $
