Let cp be x Loss%=10% of x =10x/100 Sp=cp - loss 2000=x-10x/100 2000=x-90x/100 2000×100/90=x 2222.23(app.)=x So cost price is 2222.23 (approx )

Yogita Ingle 7 years ago

Let l, b, h represent length, breadth and height of the cuboid.

Area of the rectangular base of the cuboid = l × b.

Volume of the cuboid = (Area of base) × (height of the cuboid) = (l × b) × h = lbh

While finding the volume of cuboid, length, breadth and height must be expressed in the same units.

Algebraic expression is totally based on using variables and constants. First thing to get well known with is like terms. For e.g. 3xz and 4xz are like term. Means they are hving same variables in end. The order of the variable may change but they will be considered as like term. Means xz and zx are similar. Next u need to learn identities which are 1.(a+b) whole sq. =a sq.+b sq.+2*a*b 2.(a-b)whole sq. =a sq. +b sq. +2*a*b 3.a sq.-b sq. =(a+b)*(a-b) 4.x+a*x+b =x sq.+a+b*x +a*b
