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
