2. The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:
सही उत्तर: [B]
हल (Solution):
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
=> (20-x/x*100=25)
2000 - 100x = 25x
125x = 2000
x = 16.
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
=> (20-x/x*100=25)
2000 - 100x = 25x
125x = 2000
x = 16.
3.
If selling price is doubled, the profit triples. Find the profit percent.
सही उत्तर: [B]
हल (Solution):
Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x) y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
Profit % = x x 100 % = 100%
x
Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x) y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
Profit % = x x 100 % = 100%
