Correct  answer is: Rs. 7,500/-

Let sum be Rs.x
According to the question,
\(\Large \frac{x \times 10 \times 1}{100}+\frac{x \times 12 \times 1}{100} = 1650\)
\(22x = \Large 1650 \times 100\)
\(x = \Large \frac{165 \times 100}{22}\)
\(=Rs.7500\)

Interest = 3456 - 3200 = Rs.256

Therefore, Rate = $\Large \frac{S.I. \times 100}{Principal \times Time}$

=$\Large \frac{256 \times 100}{3200 \times 2}$ = 4% per annum

If the amount borrowed be Rs.x, then

$\Large \frac{x \times 4 \times 3}{100}+\frac{x \times 8 \times 2}{100}+\frac{x \times 9 \times 2}{100}$ = Rs.19550Th

=>$\Large \frac{12x}{100}+\frac{16x}{100}+\frac{18x}{100}$ = 19550

=> 12x+16x+18x

= 1955000

=> 46x = 1955000

=> x = $\Large \frac{19550000}{46}$

= Rs.42500
