Question

An article was sold at a profit of 18%.if it had been sold for $49 more, then the gain would have been 25%.The cost price of article is?​

Answer 1

Answer:

Let cost price of the article be Rs. x,

then according to the question

$125x/100 - 118x/10$

$= 49$

$⇒ (125x-118x)/100=49$

⇒ 7x = 4900

⇒ x = 700

Cost price of the article is Rs. 700

Short Trick:

Let cost of article be Rs. 100%

$25 \% - 18\% = 49$

$⇒ 7 \% = 49$

$⇒ 1 \% = 7$

$⇒ 100 \% = 700$
