Question

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

Answer 1

Answer:

(i) P = Rs. 150, R = 5% per year

T = 4 Years

∴ S.I. = P . R. T/100 = (150 × 5 × 4)/100

= Rs. 30

And amount  = P + S.I.

= Rs. 150 + Rs. 30 = Rs. 180

(ii) P =  Rs. 350, R = 8 % p.a.

T = (3.1/2 ) years =  (7/2) years

∴ S.I.  = (P × R × T)/100 =  (350 × 8 × 7)/(100 × 2)

= Rs. 98

Amount = P + S.I. = Rs. 350 + Rs. 98

= Rs. 448

Answer 2

Answer:

S.I. = P×R×T/100

S.I. = 150×4×5/100

S.I =₹30

Amount =P+S.I

Amount =₹150+₹30=₹180

S.I.=₹30,Amount =₹180
