Q:
In what time will Rs. 1860 amount to Rs. 2641.20 at simple interest 12% per annum?
Answer & Explanation
Answer: B) 3.5 years
Explanation: 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.
