Step-by-step explanation:

1200×125/300=-1200×75/100+total amount

4×125=-12×75 + total amount

500+800=total amount

total amount=1300Rs

Answer 2

$\huge \boxed {\fcolorbox{red}{aqua}{Answer}}$

Increased new value = Original value (1+percentage as fraction)

1200 (1+ $\sf{ \frac{22}{3 \times 100} }$)

1200 ( 1+ $\sf{{ \cancel \frac{11}{150}} }$) = 1288

Decrease new value = Original value (1- percentage as a fraction)

1288 (1- $\sf{{ \cancel \frac{25}{100} }})$

$\sf{ { \cancel{1288 }}} \times \sf{ \frac{3}{{ \cancel4} } =966 }$

The final amount is 966
