Question

In what time will rs 5000 amount to rs 6612.5 aptitude

Answer 1

[Sorry! but where is the rate of interest? And I also think that when it is a decimal number then after the decimal point there should be two digits.]

Although,

Principal (P) =₹5000

Amount (A) =₹6612.50

Rate of interest (R)= R% [ You have not provided]

Time (T) = T

Simple interest (S.I.) = (6612.50-5000.00)

                                 =rs. 1612.50

∴ T = (S.I.×100)/(P×R)

        = (1612.50×100)/ (5000×R)

        = 161250/5000R

          = 3225/100R

         = 645/20R

         = (129/4R) Years

[ Put, the value of 'R' and calculate the rest then, you will get the proper answer.]
