• A. $Rs.370$
• B. $Rs.300$
• C. $Rs.400$
• D. $Rs.250$

Answer 1

The correct option is A $Rs.370$

$\Rightarrow$ Cost of $1m$ shirt material $=Rs.50$

$\Rightarrow$ Cost of $1m$ trouser material $=Rs.90$

$\Rightarrow$ Cost of $2m$ shirt material $=Rs.50\times 2$

$=Rs.100$

$\Rightarrow$ Cost of $3m$ trouser material $=Rs.90\times 3$

$=Rs.270$

$\Rightarrow$ Total cost of material $=Rs.100+Rs.270=Rs.370$
