Answer» Answer: Mark me as Brainleast ❤❤ Step-by-step explanation: Rs.1500 is invested at a rate of 10% SIMPLE INTEREST and interest is added to the principal after EVERY 5 YEARS. S.I. for the first 5 years =1500×10010×5 = Rs.750 Thus, principal for the next 5 years is = Rs. (1500+750) = Rs 2250 REQUIRED amount = Rs.2500 Let the invested amount amounts to Rs. 2500 in t years. So, 2500=2250+2250×10010×t ⇒2500−2250=225×t ⇒225×t=250 ⇒t=225250 ⇒t=910 Thus, total time required =(5+910) years =945+10 years =955 years =691 years |
