Question

Suman buys 160 chocolates for 480. She wanted to earn 30% profit by selling them. But Rakesh
visited her and she gave him 25% of those chocolates at the cost price itself. But even after doing this,
she earned a profit of 30% as decided. For how much did she sell each chocolate?​

Answer 1

Answer:

the answer is 3.9

Suman buys 160 chocolates for 480.

so the cost of one chocolate is 3.

but she gave 25% of chocolates to Rakesh.

25/100*160 = 40

then remaining chocolates are 160-40 is equal to 120.

remaining cost of chocolates are 120 x 3 is equal to 360.

now she earned a profit of 30%.

then

30/100*360 = 108

then

360 Plus 108 is equal to 468

so Suman earned 468

then

she sell chocolates by 468/120 = 3.9

Answer 2

Answer:

Given :Total chocolates = 160 for price 480

To find : SP of 1 chocolate

Explanation:

cost price of the 1 chocolate =  = Rs. 3

profit of 160 chocolates =

30% of 480

$\frac{30}{100}$ × 480

= Rs. 144

on giving 25% that means

$\frac{1}{4}$ of the cost price

i.e

160-40 = 120 chocolates

then

SP-CP = profit on 1 chocolate

total profit = 120 x (p - cp)

144 = 120 x (p - 3)

thus , The price of 1 chocolate is Rs, 4.2
