Exercise- 12G MCQs
( Fundamental Concepts of Algebra Class 6 RS Aggarwal Goyal Brothers ICSE Maths Solutions Ch-12 )
Que-1: The sum of 6x and 2y is
(a) 8x (b) 8 (x+y) (c) 8+x+y (d) none of these
Sol: (d) none of these
Reason: the sum of 2x and 6x is
= 6x+2x
= 8x.
So, the option ‘D’ is correct
Que-2: (6×a×a×3×b×b×b×2×c×c×c×c) = ?
(a) 36(a²+b³+c⁴) (b) 35a²b³c⁴ (c) 11a²b³c⁴ (d) none of these
Sol: (b) 35a²b³c⁴
Reason: 6×a×a×3×b×b×b×2×c×c×c×c
= 6×3×2×a×a×b×b×b×c×c×c×c
= 35a²b³c⁴.
Que-3: If x = 3 and y = -2, then the value of (7x-9y+2) is
(a) 5 (b) 41 (c) 23 (d) none of these
Sol: (b) 41
Reason: 7x-9y+2
x = 3 and y = -2
= 7(3)-9(-2)+2
= 21+18+2
= 41.
Que-4: If x = 1/2 and y = 1/4, then the value of (16x+8y-10) is
(a) -1 (b) 1 (c) -2 (d) 0
Sol: (d) 0
Reason: 16x+8y-10
x = 1/2 and y = 1/4
= 16(1/2)+8(1/4)-10
= 8+2-10
= 0.
Que-5: If a+2b = 5 and c = 3, then the value of a+2(b-c) is
(a) 1 (b) -1 (c) 11 (d) -11
Sol: (b) -1
Reason: a+2b = 5
a = 5-2b
c = 3
a+2(b-c)
= (5-2b)+2(b-3)
= 5-2b+2b-6
= -1.
Que-6: 9 taken away from the product of x and y is
(a) 9-xy (b) xy-9 (c) 9-(x/y) (d) (x/y)-9
Sol: (b) xy-9
Reason: Let the number be x and y
product = xy
9 taken away from the product is
= xy-9.
Que7: In (-7/8)a²b, the coefficient of b is
(a) -7/8 (b) (7/8)a² (c) (-7/8)a² (d) (-7/8)a²
Sol: (c) (-7/8)a²
Reason: The coefficient of b is
-(7/8)a².
Que-8: The degree of x²y²+3xy²-5xy is
(a) 2 (b) 3 (c) 4 (d) 0
Solution- (c) 4
Reason: Degrees of xy
= 2+2
= 4.
Que-9: 6a+(-3b)+(-2a)+(-4b) = ?
(a) 4a-7b (b) -10ab (c) -3(a+b) (d) none of these
Sol: (a) 4a-7b
Reason: 6a+(-3b)+(-2a)+(-4b)
= 6a-3b-2a-4b
= 4a-7b
Que-10: Twice a variable added to 4 is added to 3 subtracted from thrice the same variable. This statement can be written as
(a) (2x+4)-(3x-3) (b) (4+2x)+(3x+3) (c) (2x+4)+(3-3x) (d) none of these
Sol: (b) (4+2x)+(3x+3)
Reason: Let the variable be x
So, Twice it and add 4 is
(2x+4)
And, Add the thrice and subtract 3 is
(2x+4)+(3x+3)
