(1). 60

(2). 72

(3). 80

94). 96

(2). 2

(3). 6

(4). 8

7. If a clock strikes appropriate number of times at each hour ,how many times will it strike a days ?

(1). 300

(2). 156

(3). 68

(4). 78

8. A farmer can plough a field working 6 hours per day in 18 days. The worker has to work how many hours per day to finish the same work in 12 days ?

(1). 7

(2). 9

(3). 11

10. If Rs.126.5 is divided among A,B,and C in the Ratio of 2:5:4 ,the share of B exceeds that of A by

(1). Rs.36.50

(2). Rs.35.50

(3). Rs.34.50

(3). Rs.33.50

Answers and Solution:

1.(4)

2.(2)

LCM of 10 ,15 and 20 = 60

Largest 4-digit number = 9999

So required number = 9999-39 = 9960

3.(3)

4.(3)

Boys = x

Girls = z-x

so parts of girls = z-x/z = 1-x/z

5.(4)

6.(4)

Unit's digit in 3*38*537*1256

= unit digit in 3*8*7*6

= 4*2 = 8

7.(2)

8.(2)

D1T1 = D2T2

=> 18*6 = 12*T2

=> T2 = 9 hours

9.(3)

10.(3)

A:B:C = 2:5:4

sum of ratios = 2+5+4 = 11

Difference = (5/11 - 2/11)*126.50

= Rs.34.50
