A) .7%

B) 0.5%

C) 0.9%

D) 0.3%

**ANSWERS AND SOLUTION:**

1 (C) Let the numbers be 12x and 12y.

Their LCM = 12xy when x and y are prime to each other.

so Y = 1056/132 = 8 [12x = 132]

Other number = 12y

= 12 * 8 = 96

2 (C) Here, the first divisor 192 is a multiple of second divisor 16.

so Required remainder

= remainder obtained by dividing 54 by 16 = 6

3 (B) Jyothi can do 3/4 th of a job in 12 days.

Jyothi can do 1 job in (12 *4)/3 = 16 days.

As Mala is twice as efficient as Jyothi.

so Mala will finish the job in 8 days.

4 (C) According to the question,

If A takes x days to complete the work, B will take 2x days and C will take 4x days,

Now, (A + B)’s 1 day’s work

= 1/4

= 1/x + 1/2x= 1/4

= (2+1)/2x = 1/4

2x = 12

X = 6

C will complete the work in 24 days.

5 (B) Sum of the volumes of two cylinders

= Ï€r1^2 h1+ Ï€r2^2 h2

= 22/7 (4 * 4 * 6 + 5 * 5 * 4)

= 22/7 (96 + 100)

= 22/7 * 196 = 616 cm3

Let the radius of the disc be r cm.

so Ï€r^2*1=616

= 22/7 * r^2 = 616

= r^2 = (616 * 7)/22 = 196

r = √196 = 14 cm

**6.(A)**

**7.(A)**

**8. (C)**

**9. (A)**

**10. (B)**
