Question

Find the interest and amount on:
(a) ₹750 in 3 years 4 months at 10% per annum.

(b) ₹5000 at 8% per year from 23rd December 2011 to 29th July 2012.​

Answer 1

Answer:

a) Principal (P)= ₹750

Time (T)=3 years 4 months = 40 months = 40/12 years

Rate (R) = 10 % per annum

simple interest = P x RxT/100

=> ₹750x10x 40/100x12

=> ₹250

Interest (I)=₹250

Amount = P+I=₹750+₹250 = 1000₹

Answer 2

Answer:

here interest which is called principle interest is rupees 750 of (a) and is rupees 5000 of (b) and amount is given below..

Step-by-step explanation:

(a). simple interest=P.R.T/100=750*40*10/100*12=3000/12=250

(b) simple interest=PRT/100

here P=5000, R=8, T=23months + 6days

therefore, 5000*8*23+6/100*12=50*2*25=100*25=2500..
