Correct Answer: (1)
Solution: (1)
Let, Sum lent at $6 \%$ rate of interest $= \text{₹} x$
$ \text { S.I. }=19000-16800 $ $ = \text{₹} 2200 $
$ \therefore \frac{x \times 6 \times 2}{100}+\frac{(16800-x) \times 8 \times 2}{100}$ $ =2200 $
$ \Rightarrow 12 x+16800 \times 16-16 x $ $ =220000 $
$ \Rightarrow 4 x=268800-220000 $
$ \Rightarrow 4 x=48800 $
$ \Rightarrow x= \text{₹} 12200$
