Answers:

1.Answer: c

X:y=1:7

Y:z=1:3

X   :   y:  z

1   :  7

1:    3

1:     7:     21=>x: y: z

Therefore, x:z= 1:21

2.Answer: a

Let the two numbers be 7x and 5x respectively.

7x*5x=7875

X²=225=> x=15

Difference of two numbers= 2*15=30

3.Answer: a

Let the salaries be x, y and z respectively.

Sum of income of 3 members= 20000×3=60000

X=10000

y-z=16000

x+y+z=60000

On solving y=33000, z=17000

4.Answer: d

A+B=1/12

A+B+C+D=1/6

A=1/20=>C=1/60

A+B+C=1/12+1/60=1/10

D=A+B+C+D-(A+B+C) = 1/6-1/10=1/15

D alone can complete the work in 15 days.

5.Answer: d

x5/4, x6/4, x7/4, x8/4 series

6.Answer: b
