• D. Rs. $736$

Answer 1

The correct option is C Rs. $726$

Cost of setting of magazine$=1000$
Cost of printing $100$ copy of magazine $=120$
$\therefore$ Cost of $900$ copy$=120\times 9=1080$
Cost of ink etc$=60\times 900=540$
Total cost $=1000+1080+540=$ Rs. $2620$
SP of $784$ magazine $=784\times 2.76=$ Rs. $2156$
For getting Profit of $10$%
he should get $=\frac{110}{100}\times 2620=2882$
amount to recover $=2882-2156=$ Rs. $726$
