A customer borrowed 2000 and then further 1000 both repayable in 12 months .What would he have saved if he had taken out one loa
creativ13 [48]

Answer:

No savings

Step-by-step explanation:

Let the interest rate be same for all the loans and consider it to be R.

<u>First case</u>

Principal 1 = 2000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

So, interest 1 = Principal * Time * Rate

                   = 2000 * 1 * R

                   = 2000R

Now,

Principal 2 = 1000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

So, interest 2 = Principal * Time * Rate

                   = 1000 * 1 * R

                   = 1000R

Total interest to be paid = 2000R + 1000R

                                         = 3000R

<u>Second case</u>

Principal = 3000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

Interest = Principal * Time * Rate

             = 3000 * 1 * R

             = 3000R

We conclude that there would be no savings because the interest to be paid in both the cases are same.

How many terms are there in the following expression? x - 5 + 16x + 4 - 2x - 3
k0ka [10]

Answer:

Two terms

Step-by-step explanation:

First, we have to simplify reducing the number of terms, since there are like terms

x-5+16x+4-2x-3

Eventually, you'll get 15x-4,  thus there are two terms.

Please correct me if I'm incorrect, and I'll change the answer, but I hope I helped :)
