Questions + Answers key
Take MCQ Maths Test1.
Multiply (2x + 5y) and (3x − 4y)
2.
Ram deposited ‘x’ number of Rs. 2000 notes, ‘y’ number of Rs.500 notes, ‘z’ number of Rs.100 notes in a bank and Velan deposited ‘3xy’ times of amount of what Ram had deposited. How much amount did Velan deposit in the bank?
3.
Find the product of 2x2y2, 3y2z and –z2x3
4.
If the length and breadth of a rectangular painting are 4xy3 and 3x2y. Find its area.
5.
If the side of a square carpet is 3x2 metre, then find its area
1.
= 6x2 − 8xy + 15xy − 20y2
= 6x2 + 7xy− 20y2(simplify the like terms
2.
Amount deposited by Ram
= (x × Rs.2000 + y × Rs.500 + z × Rs.100)
= Rs.( 2000x + 500y + 100z )
Amount deposited by Velan = 3xy times × Amount deposited by Ram
= 3xy × (2000x + 500y + 100z)
=(3 × 2000)(x × x × y)+(3 × 500)(x × y × y)+(3 × 100)(x × y × z)
= (6000x2y + 1500xy2+ 300xyz)
3.
We have, (2x2y2) × (3y2z) × (−z2x3)
= (+) × (+) × (−)(2 × 3 × 1)(x2 × x3)(y2 × y2)(z × z2)
= − 6x5y4z3
4.
Area of the rectangular painting, A = (l × b) sq.units
= (4xy3) × (3x2y)
= (4 × 3)(x × x2)(y3 × y)
A = 12x3y3 sq.units.
5.
The area of the square carpet, A = (side × side) sq. units.
= 3x2×3x2
= 3×3×x2×x2
A = 9x4 sq.m
