Question

Rajan purchased 250 packets of blades at the rate of of rupees 8 per packet he sold 70% it is the packet @ rupees 11 per packet and remaining packet @ rupees 9 per packet find his gain percent

Answer 1

Profit gained by Rajan is 30%

Step-by-step explanation:

1 packet cost rs 8.

250 packets cost rs 250 × 8 = rs 2000.

Therefore, cost price = rs 2000.

He sold 70% packets at the rate of rs 11.

No. of packets sold = 250×70÷100 = 175 packets.

175 packets were sold at the rate of rs 11.

Therefore, selling price of 175 packets is 175 × 11 = rs 1925.

He sold remaining 30% packets at the rate of rs 11.

No. of packets sold = 250×30÷100 = 75 packets.

Therefore selling price of 75 packets = 75 × 9 = rs 675.

Total selling price= 1925+675 = rs 2600.

He gained a profit of rs 600.

profit percent= (selling price - cost price) × 100 ÷ cost price i.e (2600-2000) ×100 ÷ 2000 = 30%.

Therefore, he gained a profit of 30%.

Answer 2

$\huge \pink{ \boxed{ \boxed{ \mathfrak{solution}}}}$

cp=250×8

=₹2000(actual cp)

$\blue{70\% \: of \: 250}$

$\pink{ \frac{70}{100} \times 250}$

$\blue{7 \times 25}$

$\pink{ = 175}$

$\blue {sp \: of \: 175 \: packets = 175 \times 11}$

$\pink{ = 1925}$

$\blue \therefore \blue{30\%of \: 250 = 250 - 175}$

$\pink{ = 75}$

$\blue{sp \: of \: 75 \: packets = 75 \times 9}$

$\pink{ = 675}$

$\huge \green{ \underline{ \underline{now}}}$

$\blue{total \: sp = 1925 + 675}$

$\pink { = 2600(actual \: sp)}$

$\orange{ \boxed{profit = sp - cp}}$

$\blue{2600 - 2000}$

$\pink{ = 600}$

$\red{ \boxed{profit\% = \frac{profit}{cp} \times 100}}$

$\blue \implies{profit\% = \frac{600}{2000} \times 100}$

$\implies \: profit\% = 30\%$
