Question
The price of a commodity was
first increased by 25% and then decreased by 25%. If the new price of the commodity is Rs. 600, find the original price of the commodity.Solution
ATQ,
Let the original price of the commodity be Rs. '100x'. New price of the commodity = 100x × 1.25 × 0.75 = Rs. '93.75x' So, 93.75x = 600 x = 600 / 93.75 = 6.4 Therefore, the original price of the commodity = 100 × 6.4 = Rs. 640.
Given a triangle with two sides measuring 12 cm and 16 cm, which of the following cannot be a possible length for the third side?
- Find the remainder on dividing (5x 3  + 4x 2  – 10x + 1) by (2x – 4).
The area (in sq, units) of the triangle formed by the graphs of 8x + 3y = 24, 2x+8 = y and the x – axis is:
If x −y =4and xy =45,thenthevalueof x 3 −y3is:
If x + y = 2 and 1/x + 1/y = 18/15, then find the value of (x3 + y3)?
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If y + 1/y = 2 then find y117 + 1/(y117)
if a2 + b2 + c2Â =Â 2(4a -5b -9c)-122 , then a-b-c = ?
If a – b – c = 0, then the value of (a2 + b2 + c2)/(b + ac) is:
If 5x - 13xy + 6y = 0, find x : y.
