1.	A debt of Rs. 21,840 is due in 3 years at 12% per annum at simple interest. Calculate the value of annual installment.1. Rs. 7862.402. Rs. 6503. Rs. 58714. Rs. 65005. None of these.
Answer» Correct Answer - Option 4 : Rs. 6500 Given: Total amount = Rs. 21,840 Time = 3 years Rate = 12% per annum at SI Formula used: For installment at SI, A = nx + {(n – 1) + (n – 2) +(n – 3) + …}Rx/100 where, A = Total amount or Debt. x = value of each installment n = time for installment R = Rate (%) Calculations: A = nx + {(n – 1) + (n – 2) +(n – 3) + …}Rx/100 ⇒ 21840 = 3x + (2 + 1)12x/100 ⇒ 21840 = 3x + (36x/100) ⇒ 21840 = 336x/100 ⇒ 21840/336 = x/100 ⇒ 65 = x/100 ⇒ 6500 = x ∴ Annual installment is Rs. 6500

Answer» Correct Answer - Option 4 : Rs. 6500

Given:

Total amount = Rs. 21,840

Time = 3 years

Rate = 12% per annum at SI

Formula used:

For installment at SI,

A = nx + {(n – 1) + (n – 2) +(n – 3) + …}Rx/100

where,

A = Total amount or Debt.

x = value of each installment

n = time for installment

R = Rate (%)

Calculations:

A = nx + {(n – 1) + (n – 2) +(n – 3) + …}Rx/100

⇒ 21840 = 3x + (2 + 1)12x/100

⇒ 21840 = 3x + (36x/100)

⇒ 21840 = 336x/100

⇒ 21840/336 = x/100

⇒ 65 = x/100

⇒ 6500 = x

∴ Annual installment is Rs. 6500
