What annual installment will discharge a debt of Rs. 1092 due in 3 years at 12% simple interest ?

A) Rs. 300

B) Rs. 350

C) Rs. 400

D) Rs. 325

E) Rs. 320

Option D

Let installment be $x$

Then $\left\{x+\frac{(x\times 12\times 1)}{100}\right\}$ $+\left\{x+\frac{(x\times 12\times 2)}{100}\right\}$ $+x$ $=1092$

$x$ = Rs.325
