Question

find the interest and amount on rs.4000 for 5 years at 10% per annum ​

Answer 1

Answer:

A=P(1+r100)n⇒A=4000(1+10100)2⇒A=P(1+110)2⇒A=4000(1110)2⇒A=4000×121100⇒A=4840 Rs. Hence the amount after 2 years will be 4840 and it'll only work as the principal amount for simple interest. The formula for the simple interest is = PRT100, where P is the principal amount, R is the rate of interest, and T is time spam.

Answer 2

Answer:

Principal = rs. 4000

time = 5 years

Rate = 10%

Amt = p(1+r/100)n

Amt = 4000(1+10/100)⁵

= 4000(1+10/100)⁵

= 4000(100+10/100)⁵

= 4000(110/100⁵)

= 4000×110/100×110/100×110/100×110/100×110/100

= 64,420.4 ans

C.I = Amt - Principal

= 64,420.4-4000

= 60,420.4 ans.
