Select the correct answer in each of the following:

1. If 2x-3=x+2, then x=?

(a)1 (b) 3 (c)5 (d) 7

Solution:

(c)5

Explanation:

Given 2x-3=x+2

By transposing we can write as 2x-x=2+3

Therefore x=5

2. If 5x+(7/2)=(3/2)x-14, then x=?

(a)5 (b) -5 (c)6 (d) -6

Solution:

(b) -5

Explanation:

Given 5x+(7/2)=(3/2)x-14

On rearranging we get

5x+(3/2)x=(7/2)-14

Taking L.C.M we get

(10x-3x)/2=(-28-7)/2

7x=-35

x=-5

3. If z=4/5(z+10), then z=?

(a) 40 (b) 20 (c) 10 (d) 60

Solution:

(a) 40

Explanation:

Given z=4/5(z+10)

By cross multiplying

z-(4/5)z=40/5

By taking L.C.M

z/5 =40/5

z=40

4. If 3m=5m-(8/5), then m=?

(a) 2/5 (b) 3/5 (c) 4/5 (d) 1/5

Solution: (c) 4/5

Explanation:

By cross multiplying 5m-3m=8/5

2m=8/5

m=4/5

5. If (5t-3) = 3t-5, then t=?

(a) 1 (b) -1 (c) 2 (d) -2

Solution:

(b) -1

Explanation:

By transposition 5t-3t=-5+3

2t=-2

t=-1

6. If 2y+(5/3)=(26/3)-y, then y=?

(a) 1 (b) 2/3 (c) 6/5 (d) 7/3

Solution:

(d) 7/3

Explanation:

Given 2y+(5/3)=(26/3)-y

On rearranging, 2y+y=(26-5)/3

3y=7

y=7/3

7. If (6x+1)/3+1=(x-3)/6, then x=?

(a) 1 (b) -1 (c) 3 (d) -3

Solution:

(b) -1

Explanation:

Given (6x+1)/3+1=(x-3)/6,

On rearranging, 12x-x=-3-8

x=-1

8. If n/2-3n/4+5n/6=21, then n=?

(a) 30 (b) 42 (c) 36 (d) 28

Solution:

(c) 36

Explanation:

Given n/2-3n/4+5n/6=21

On rearranging and taking L.C.M,

(6n_9n+10n)/12=21

7n=21(12)

n=36

9. If (x+1)/(2x+3)=3/8, then x=?

(a) 1/4 (b) 1/3 (c) 1/6 (d)1/2

Solution:

(d) 1/2

Explanation:

Given (x+1)/(2x+3)=3/8,

On rearranging, 8(x+1)=3(2x+3)

8x-6x=9-8

2x=1

x=1/2
