Question

in what time will rupees 1860 amount to Rupees 2641.29 at simplest interest of 12% per annum​

Answer 1

Answer:

Amount = Rs. 2641.29

Principal = Rs. 1860

S.I = (A-P)

= Rs. (2641.29-1860)

= Rs. 781.29

Time = (S.I*100) / (P*R)

= (781.29*100) / (1860*12)

= 3.5 years

Hope this helps.

Answer 2

"3.5 years" is the correct answer.

Given that Rs. 1860 will become Rs. 2641.20 at 12%

=> Simple Interest = 2641.20 - 1860 = Rs. 781.20

We know I = PTR/100

=> 781.20 x 100 = 1860 x T x 12 => T = 78120/1860x12 => T = 78120/22320

=>T = 3.5 years.

Hope it helps you:)
