Question

1. Find the S.I. and the amount on :
(i) 150 for 4 years at 5% per year.​

Answer 1

Answer:

Step-by-step explanation:

P = 150

R= 5

T= 4

So, S =P×R×T/100

= 150×5×4/100

= 15

AMOUNT = P+SI =150 + 15 = 165

Answer 2

Answer:

SI = Rs.30

Amount = Rs.180

Step-by-step explanation:

P = principal / initial amount in Rs. = 150

R = rate of interest per cent per year = 5

T = time period in years = 4

A = amount at the end of time period T

SI = Simple Interest = (P*R*T)/100

A = P + SI

On substituting the values:

SI = (150*5*4)/100

    = 3000/100

     = 30

A = P + SI

   = 150 + 30

    = 180

Final answer

SI = Rs.30

Amount = Rs.180
