Answer 1

S. P OF BOOK FOR C=144
GAIN %=4
THEREFORE..... CP OF BOOK(FOR C)
=(144*4)/100+144
=5.76 + 144
=149.76 or 150(aprox.)

NOW SP OF BOOK FOR B=150
GAIN BY A=20%
THEREFORE CP =150-(150*20)/100
=150-30
=120.....

Answer 2

Let the cost price of that article be ' x '

A sells it to B at a profit of 20%

Selling price = cost price + profit

Profit = cost price×profit percentage

so x + 20%×x =x + x×20/100 = x + 0.2x = 1.2x

B sells to C ata loss of 4% if C pays rupees 144

Selling price = cost price - loss

Loss= cost price× loss percentage

1.2x - 4% × 1.2x = 144

1.2x - 1.2x × 4/100 = 144

1.2x - 0.048x = 144

1.152x = 144

x = 144/1.152

x= 120 = cost price
