Answer 1

Answer:

5400 Rs

Step-by-step explanation:

Since this is a simple interest, therefore, we will have to calculate each one separately.

The total amount to be paid = 19350 (principal)+ the simple interest for the 4 years.

Let each annual installment be 'x'. The amount to be paid each year will be deducted from the principal.

For the first year, the interest = 19350*0.05 = 967.5

After one year, the principal will be reduced to 19350-x.

The interest for the 2nd year = (19350-x)*0.05 = 967.5-0.05x.

After 2 years, the principal will be 19350-2x.

The interest after 2 years will be (19350-2x)*0.05= 967.5-0.1x

After 3 years, the principal will be 19350-3x

The interest after 3 years will be (19350-3x)*0.05 = 967.5-0.15x

Therefore, the total to be paid after 4 years = 19350 + 4(967.5)-0.05x-0.1x-0.15x; which is equals to 4x (the annual installments over the 4 years).

19350 + 4(967.5)-0.05x-0.1x-0.15x=4x

23220 = 4.3x

x = 5400

So, option B is correct.
