Answer 1

Hey Dear ... ✌️

_____________________________

=) Let the sugar sold at 8% gain = x

Therefore, Sugar sold at 18% gain = (1000 - x)

Let CP of sugar = Rs.y per kg

Total CP = Rs.100y

Therefore,

$( \frac{108}{100} \times xy) + \frac{118}{100} (1000 - x)y \\ \frac{114}{100} \times 1000y \\ 108xy + 118000y - 118xy = 114000y \\ 10x = 4000 \\ x = 400$

Quantity sold at 18% profit

= 1000 - 400 = 600 kg
