Question

To what amount will ₹12000 accumulate in 12 years if invested at an effective rate of 5%?​

Answer 1

Answer:

The rate is 600 per year at 12 years result to 7200 when the total now is 19,200

investment is calculated by multiplying the rate by the number of years with the yearly amount added to the principal amount

the total is 19,200

Answer 2

Answer:

The amount after 12 years will be Rs 21558

Step-by-step explanation:

In the above question:

Given:

Principle= Rs 12000

Interest= 5%

    Time= 12years

To find:

Amount?

Solution:

To find the amount, we know the formula as:

A= P(1+r/100)^n

  = 12000(1+5/100)^12

  = 12000(1+1/20)^12

  = 12000(20+1/20)^12

  = 12000(21/20)^12

Now, since it is a huge number to calculate we take log(logarithm on both sides)

We get,

log A= log 12000+ 12(log21-log20)

        = 4.0792+ 12(1.3222-1.3010)

        = 4.0792+ 12(0.0212)

        = 4.0792+ 0.2544

        = 4.3336

log A= 4.3336

     A= antilog(4.3336)

      = 21,558

Therefore, amount= Rs 21,558
