If $120 invested at a certain rate of simple interest amounts to $160 at the end of 3 years,How much will $150 amount to at the same rate of interest in 6 years?
Answer/Solution
$250
Steps/Work
120 amounts to 160 in 3 years.
i.e (principal + interest ) on 120 in 3 years = 160
120 + 120*(r/100)*(3) = 160 => r = 100/9
150 in 6 years = principal + interest
= 150 + 150*(r/100)*(6)
250
Answer is E.
i.e (principal + interest ) on 120 in 3 years = 160
120 + 120*(r/100)*(3) = 160 => r = 100/9
150 in 6 years = principal + interest
= 150 + 150*(r/100)*(6)
