Question

A shopkeeper buys 30 chocolate bars at RS 15 each and sold all of them for RS 525 find it profit percent he made

Answer 1

$\bold {\huge {Solutions :-}}$

1 chocolate cost = Rs 15
30 chocolate cost = Rs 15 × 30 = Rs 450

$\bold {\underline {So, ~we~ have}}$

CP = Rs 450
SP = Rs 525

Profit = SP - CP
= RS (525 - 450)
= RS 75

Profit % = profit/CP × 100 %
= 75/450 × 100 %
= 16.66%

$\bold {\underline {Hence,}}$

$\bold {Profit~ percent~ = ~16.66}$% approx.

Answer 2

C.P of 30 chocolates =15×30=RS450
S.P of 30 chocolates=RS525
profit=525-450=RS75
profit percent=75×100/450
=16.66%
