sells it to C at a profit of 25%. If C pays 225 for it, what did A
pay for it​

Answer 1

ANSWER

Let cost price for A=100rs

Sp for A=cp for B=100+10020×100

=120

Sp for B=Cp for C=120+25% of 120

=120×10025×120

=150

Given,

CP for C=225

So, 150→225

1→150225=23

100→23×100=

Answer 2

Answer:

150

Step-by-step explanation:

Let cost price for A=100rs

SP for A =CP for B =100+20/100×100

=120

SP for B =CP for C =120 +25% of 120

=120×25/100×120

=150

Given ,

CP for C=225

So,150=>225

1=>225/150=3/2

100=>3/2×100

=150
