Question

Ranjan purchase 250 packets of blades at the rate of rupees 8 per packet he sold 70% of the packates at the rate of 11 rupees per packet and remaining packets at the rate of 9 rupees per packet find his gain percent

Answer 1

cp of 250 packets=250*8=2000
sp of 70% of 250=175*11=1925
sp of 75 packets =75*9=675
profit=600
%profit=30%

Answer 2

$\large{\boxed{\bold{Answer:}}}$

Total packets - 250

Cost of 1 packet = 8rs

Cost of 250 packets = 250×8 = 2000

$70\% \: of \: 250 = \frac{70}{100} \times 250 = 175$

S.P of 175 packets = 175×11

= 1925rs

Remaining packets = 75

S.P of remaining packets = 75×9 = 675rs

Total S. P = 1925+ 675 = 2600rs

Profit = 2600 - 2000 = 600rs

$= \frac{600}{2000} \times 100 = 30\%$

Hence, the profit is 30%
