1. A square garden has fourteen posts along each side at equal interval. Find how many posts are there in all four sides:

(a)   56 (b) 52 (c) 44 (d) 60

Exp   1. (b) Reqd no. of posts = 4 (at the corners) + 4 × 12 (in between on the sides)= 4 + 48 = 52

2. Average age of students of an adult school is 40 years.120 new students whose average age is 32 years joined the school. As a result the average age is decreased by 4 years. Find the number of students of the school after joining of the new students:

(a)   1200 (b) 120 (c) 360 (d) 240

Exp   2. (d) Let the original no. of students be x A.T.S. 40x + 120 × 32 = (x + 120)36 ? x = 120 ? Reqd no. of students after joining the new students = x + 120 = 240

3. When Rs 250 added to 1/4th of a given amount of money makes it smaller than 1/3rd of the given amount of money by Rs 100. What is the given amount of money?

(a)   Rs 350 (b) Rs 600 (c) Rs 4200 (d) Rs 3600

Exp   3. (c) Let the given amount be Rs x A.T.S-x  -  (x/4-250)=100=x=Rs.4200                                          3

4. Find the least number of candidates in an examination so that the percentage of successful candidates should be 76.8%:

(a)   500 (b) 250 (c) 125 (d) 1000

Exp   (c) No. of successful candidates = 76.8% of x x = total students=(768/10x100 x X)=96/125x Which must be a whole no. ? The reqd least no. = 125

5. The number of times a bucket of capacity 4 litres to be used to fill up a tank is less than the number of times another bucket of capacity 3 litres used for the same purpose by 4. What is the capacity of the tank?

(a)   360 litres (b) 256 litres (c) 48 litres (d) 525 litres

Exp   X/4 - X/3= 4=X= 48 l

(a) 24 (b) 20 (c) 15 (d) 25

Exp   (d) Reqd no. of students = 30 x 5/6 (30/x=6/5)

7. The ratio of daily wages of two workers is 4 : 3 and one gets daily Rs 9 more than the other, what are their daily wages?

(a) Rs 32 and Rs 24 (b) Rs 60 and Rs 45(c) Rs 80 and Rs 60 (d) Rs 36 and Rs 27   Exp          X+9/X=4/3=X=27 Their daily wages are Rs 27 + 9, Rs 27 i.e. Rs 36, Rs 27

  8. Find the ratio of purchase price and sell price if there is loss of 12&1/2%=

(a)   7 : 8 (b) 8 : 7 (c) 2 : 25 (d) 25 : 2

Exp   Reqd ratio C.P/S.P100/100-25/2=8/7 S.P-C.P-Loss 8:7

  9. The simplified value of 1.2 + (1.2)2 + (1.2)3 is:

(a)   4.248 (b) 4.368 (c) 3.248 (d) 3.368

Exp  1.2 + 1.44 + 1.728 = 4.368
