Correct Answer: (1)
Solution: (1)
Let the C.P. of article A be Rs. 100.
$\therefore$ C.P. of article B $=$ Rs. 120
Marked price of article B $=$ Rs. $\left(\frac{120 \times 120}{100}\right)=$ Rs. 144
Difference between marked price and C.P. for article B $=$ Rs. $(144-120)=$ Rs. 24
$\therefore$ Marked price of article A $=$ Rs. 124
S.P. of article $A=\frac{124 \times 90}{100}$ $=$ Rs. 111.6
S.P. of article B $=\frac{144 \times 90}{100}=$ Rs. 129.6
Difference $=$ Rs. $(129.6-111.6)$ $=$ Rs. 18
If the difference of S.P. is Rs. 18,
C.P. of article $A=$ Rs. 100
If the difference of S.P. is Rs. 45 ,
C.P. of article $A=\frac{100}{18} \times 45$ $=$ Rs. 250
