Question

Rajan purchased 250 packet of blade at the rate of rupee 8 pr packet .he sold 70%of the packet at the rate of ₹11per packet and remaining packet at the rate of ₹9per packet .find the gain percent.plss solve this method with process.....plsss.......

Answer 1

SO HE PURCHASED PACKETS=250
C.P.=(8*250=2000)
70% OF 250
70/100*250=175
S.P OF 70% PACKETS=175*11
=RS.1925
REMAINING PACKETS=75
S.P OF REMAINING PACKETS=75*9
=RS.675
TOTAL S.P.=2600
GAIN=2600-2000
=600
GAIN%=600/2000*100
=30%

Answer 2

$\mathbb{ SOLUTION }$:

Total number of packets of blades = 250
Cost of each packet = ₹ 8
So,
C.P of 250 packets of blades
= 8 × 250 = ₹ 2000

70% of 250 packets of blades were sold at rate of ₹ 11 per packet.

$\frac{70}{100} \times 250 = 175$

So,
175 packets of blades were sold at ₹ 11 per packet.
S.P = 11 × 175 = ₹ 1925

Remaining packets = 250 - 175 = 75
So,
75 ( remaining packets ) were sold at ₹ 9 per packet
S.P = 9 × 75 = ₹ 675

Total C.P = 1925 + 675 = ₹ 2600

Now,
C.P < S.P = Profit

Profit = S.P - C.P
Profit = 2600 - 2000 = ₹ 600

$Profit\% = \frac{Profit}{C.P} \times 100 \\ \\ Profit\% = \frac{600}{2000} \times 100 = 30 \%$
