annum, find the amount the woman 1 9. If? 12800 be borrowed for 3 years at the rate of 6 \times \frac{1}{2} p.a., find the C.I. to be paid on it
Answers
Answer:
It is given that
Principal = ₹ 46875
Rate of interest = 4% p.a.
(i) Interest for the first year = Prt/100
Substituting the values
= (46875 × 4 × 1)/ 100
= ₹ 1875
So the amount after first year or principal for the second year = 46875 + 1875 = ₹ 48750
Here
Interest for the second year = (48750 × 4 × 1)/ 100
So we get
= ₹ 1950
(ii) We know that
Amount at the end of second year = 48750 + 1950
= ₹ 50700
(iii) Interest for the third year = (50700 × 4 × 1)/ 100 = ₹ 2028
