Correct Answer - Option 1 : Rs. 676
Given:
The principal is Rs. 1275
Rate of interest is 4 %
Number of installment is 2.
Formula used:
P( 1+ R/100)n = X( 1+ R/100)n-1 + X( 1+ R/100)n-2 + X( 1+ R/100)n -3 + X( 1+ R/100)n-4 + ----
Where,
P = principal
R = Rate
n = number of installments
X = amount of installment
Calculation:
Let the value of installment be Rs. X
⇒ 1275(1 + 4/100)2 = X(1 + 4/100)2-1
⇒ 1275 × 104/100 × 104/100 = (X + 104 X/100)
⇒ 1275 × 104/100 × 104/100 = 204 X/100
⇒ X = 676
∴ The value of installment is Rs. 676.
