Question

Find the principal and the amount for the following (a) SI= rs375 R= rs 6 percentage T =2 years 6 months​

Answer 1

Time = 2 years 6 months

first convert month to year-

6 months = 6 / 12 = 1/2 years

now , 2 years + 1/2 years = 2.5 years.

Principal = I x 100 / R x T

= 375 x 100 / 6 x 2.5

= 2500

therefore , principal is 2500
