Question 6
Consider the following quotients : 1) 368.39 divided by 17 2) 170.50 divided by 62 3) 875.65 divided by S3 Their correct sequence in decreasing order is :
A. 1, 3, 2
B. 2, 1, 3
C. 2, 3, 1
D. 3, 1, 2

Correct Op: A
1) 36839/17 = 2167,Dividend contains 2 places of decimal So,3.68.39 / 17=21.67 2) 17050/62 = 275 ,Dividend contains 2 places of decimal So,170.50/62 = 2.75 3) 87565/83 = 1055,Dividend contains 2 places of decimal So,875.65/83 = 10.55 Since 21.67>10.55>2.75 ,the desired order is 1,3,2.

Question 7

D. None of these

Correct Op: C
Let x +543+5.43 = 603.26 then x = 603.25-(543+5.43) = 603.26-548.43 = 54.83 So missing digit is 8
