A metal trader buys 2 kinds of silver foils, the ratio of their prices...
Let the prices of 2 kinds of silver be Rs 10x/kg and Rs 40x/kg.

6:1=Rs60x+Rs40x=Rs100x for 7 kg.

120%=Rs90
100%=100/120×90=Rs75/kg=cost
7kg=7×75=Rs525
100x=525
x=5.25
40x=Rs210/kg
6×52.50=Rs315
1×210=Rs210
=Rs315+Rs210=Rs525

A metal trader buys 2 kinds of silver foils, the ratio of their prices...
The selling price per kg of alloy is 90 rs
now 2 metals are mixed in proportion of 6:1 = 7
so, for (6kg+1kg) 7 kg of alloy price is 90*7= 630 rs

Their respective prices are in ratio of 1:4
consider the price to be x per kg so for alloy of 7 kg
6 kg it is 6x and for 1 kg is 4x ( as it is 4 times)
now 6x+4x=630
so x= 63rs

to cross verify,
6*63+4*63= 630
but 63 is the selling price that is 120%
so the cost price or purchase price is 63*100/120= 52.5rs
