Question

Hal Ib Its cost price?
4) Salt costs 13.50 a kilogram. 10 kg of salt
is made into packs of 500 g and sold for
155. What is the profit made if the cost
of packing is 25 p per pack?​

Answer 1

Salt costs =13.5 per kg
Given 10 kg of salt made into 500 g salt packets
For 1 kg salt(including packing)=13.5+2(0.25)
Because for 500g packing it cost =0.25 pair.
∴ For 1 kg it costs =13.5+2(0.25)
(with packing) =13.5+0.5
=14 Rs.
Now for 10 kg C.P =10×14
=140 Rs.
S.P=155 Rs.
Profit ⇒ S.P − C.P =155−140
=15 Rs.
