Q.No	Step	Answer
1	Smallest even Prime No is	2 Prime nos up to 100 = 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109
2	Complementary angle of 35 degrees	90- 35 = 55 degrees 180 – 35 degrees = 145 degrees
3	Cost of 1 dz (12 pens) = Rs.84	Hence cost of 1 pen = Rs.7, hence 7 pens = 7 x 7 =Rs.49
4	99= XCIX	Roman Numerals: 999 = CMXCIX
5	Ave of 7 Prime nos from 11	11 +13+17+19+23+29+31 = 143/ 7 = 20.12
6	SI = P x N x R / 100	5555 x 5.5 x 5 / 100 =Rs.1527.63 answer
7	Purchase price of Car is 75,000 + Fuel Rs.1500 = Rs. 76,500 , 10 % profit on it	10/ 100 * 76500 = Rs.7650 CP = Purchase Price + Expenses SP = CP + Profit = 76500 + 7650 = Rs.84,150 answer
8	CP= Rs.300, SP =Rs.270	Loss % = Loss/ CP * 100 =  30/ 300 x 100 = 30/ 3 = 10%
9	Side of a square is 5.5 m	Area= 5.5 x 5.5 =30.25 sq.m
10	Area of a circle= Pie x r x r	Circumference – 2 x pie x r
11	{(9 ÷ 3) of 3 x (3 + 2) - 5}	{3 of3 = 9 x 5 = 45 -5 = 40 answer)
12	Perimeter of a Rectangle is	2 ( L + B) = 2 (15 + 10 ) = 2 x 25 = 50 m answer
13	Triangle whose all three sides are not equal is	Scalene Triangle Two sides are equal is called- Isosceles Triangle
14	L.C.M of 13, 39 and 169.	13x 3 = 169 answer
15	Each shirt takes 3.3 m	Total cloth = 27 m Hence no of shirts that can stitched is 23/ 3.3 = 8 shirts
16	Given area of a circle is 154 sq.m	Formula area=  22/ 7 x r x r = 154 or 154/22 = 7 x 7 or 7 = 7 x 7 Or Radius = 7 Circumference is 2 = pie x r = 2 x 7 x 22/ 7 = 44 m answer
17	245 men take 5 days	Hence 7 men will take? 245 x 5 / 7 = 175 days
18	Cost of fencing @ Rs.15 / m	Fencing means Perimeter of the rectangle = 2 ( L + B ) = 2 (18 + 12) = 2 x 30 = 60 m 60 x 15 = Rs.900 Answer
19	Diagonal of a square whose side is 5 m	Diagonal of a square is  side √2 = 5 x 1.414 =7.07 m answer
20	5 seconds 200 m	In one hour? km 1 hours = 3600 seconds 3600/ 5 * 200 = 144000 m To convert into km Divide it by 1000= 144 km/hr answer
21	12 kg of sugar for Rs.18.50 per kilo, and ½ kg of rice at Rs.24 a kilo,	12 x 18.50 = Rs.222 + 12 = Rs.234 total cost Answer
22	cost of painting a circular floor of dia 28 m at Rs.30 per sq.m ?	Dia = 28. Hence r= 14 m Formula for area of a circle is 22/7 * r * r = 22/7 * 14 * 14 =616 sq m 616 x 30 = Rs.18480 Answer
23	volume of a tank whose Length is 30 m, breadth is 20 m and height is 3m.	V= l x b x h = 30 x 20 x 3 =3600 cubic m Answer
24	area of the path of a square garden of 25 m, which has a path width of 5 m.	( 5 x 20= 100)  100 sq m answer
25	What will the average weight of 3 boys if 7 boys weigh 840 kg, and ave of 4 boys is 25 kg.	7 = 840 therefore 1 boy is 120 kg 4 X 25 = 100 840 – 100 = 740 740 / 3 = 246.66 kg.
