Explanation:

Using the formula for installments for SI:

P1+R×T10 = x1+R×(T-1)10 + x1+R×(T-2)10 + ⋯ + x

Where, P = amount lent
x = equal installment, 
R = interest rate and 
T = total duration of loan.

⇒14,4001+1×510 = x1+1×410 + x1+1×310 + x1+1×210 + 1+1×110 + x

⇒ 14,4001+510 = x5+1×(4+3+2+1)100

⇒ 14,4002120 = x5+110

⇒ x ≈ 2965

Hence, 2965.
