Question
Marked price of an article is Rs.1200 more than the cost
price. When the same article is sold at a discount of Rs.200, the profit percent earned is 25%. To earn a profit of 30%, at what price the article should be sold?Solution
Let CP of an article be Rs.x And MP = Rs.(1200 + x) According to question, => (1200 + x) – 200 = [x × 125/100] => 1000 + x = 5x/4 => x = 4000 SP of an article = [(100 + 30)/100] × 4000 = Rs.5200
If x = 8.15, y = 9.06 and z = –17.21, then the value of x³ + y³ + z³ – 3xyz is:
Atul has Rs.500 with him. He invested 30% of the amount at 5% p.a. for 6 years and rest at 20% p.a. for 4 years. Find the sum of simple interests receiv...
 If x, y and z are real numbers such that (x-5)2+(y-8)2+(z-12)2= 0 then (x+y+z) is equal to
If x = 35, then the value of x5 - 36x4 + 36x3 - 36x2 + 36x - 1 is
If 3y-3/y=18 then find the value of y² +1/y²
 + Rs. 25200 is invested in 3 parts in such a way that Simple Interest on 1st Part at 4% per annum for 3 years, Simple Interest on 2nd
If 8x3Â - 125y3Â = (2x - Ay) X (Bx2Â + 25y2Â + Cxy), then find the value of 3 X (2A + 6B) - 2C.
What will come in the place of question mark (?) in the given expression?
(360 ÷ 24 + 105)% of ? = 48
