Abhi bought two articles for Rs. 624. He sold one at loss of 15% and another at a profit of 15%. If the selling price of both articles is equal. Then the difference between their cost price is?
Answer & explanation
Correct answer: option 1
15% = \(\frac{3}{20}\)
CP : SP
+15%⇒ 20 : 23 )× 17
-15% ⇒ 20 : 17 )× 23
*(to make S.P. equal, ATQ)*
CP : SP
⇒ 340 : 391
⇒ 460 : 391
Total C.P. = 800R and diff. of C.P. = 460 -340 = 120R
800R = 624
1R = \(\frac{624}{800}\) = \(\frac{78}{100}\)
120 R = 120 × \(\frac{78}{100}\) = Rs. 93.6
