Question

Two transistors together cost 480 they are sold at profit 19% other at a loss of 15% if the selling price are equal find at the cost of lower priceed one

Answer 1

Let the cost price of the lower priced one be x.

The cost of the other one will be :

480 - x

Their  selling prices :

0.85x — lower priced one

And

1.19(400 - x) = 476 - 1.19x

These two selling prices are equal.

0.85x = 476 - 1.19x

0.85x + 1.19x = 476

2.04x = 476

x = 476/2.04

X = 233.33
