1. If 6 men and 8 boys can do a piece of work in 10 days while 26 men and 48 boys can do the same in 2 days, the time taken by 15 men and 20 boys in doing the same type of work will be:
Answer: 1
Solution:Let 1 man’s 1 day’s work = x and 1 boy’s 1 day’s work = y.
Then, 6x + 8y = 1/10 and 26x + 48y = 1/2.
Solving these two equations, we get : x =1/100 and y = 1/200.
(15 men + 20 boy)’s 1 day’s work = 15/100 + 20/200 = 1/4.
=>15 men and 20 boys can do the work in 4 days.
2. If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:
Answer: 1
Solution:Let the actual distance travelled be x km.
Then, x/10 = (x + 20)/14
14x = 10x + 200
=> 4x = 200
=> x = 50 km.
3. A sum of money is to be distributed among A, B, C, D in the proportion of 5 : 2 : 4 : 3. If C gets Rs. 1000 more than D, what is B’s share?
Answer: 3
Solution:Let the shares of A, B, C and D be Rs. 5x, Rs. 2x, Rs. 4x and Rs. 3x respectively.
Then, 4x – 3x = 1000
=> x = 1000.
B’s share = Rs. 2x = Rs. (2 x 1000) = Rs. 2000.
4. A sum of money at simple interest amounts to Rs. 815 in 3 years and to Rs. 854 in 4 years. The sum is:
Answer: 3
Solution:S.I. for 1 year = Rs. (854 – 815) = Rs. 39.
S.I. for 3 years = Rs.(39 x 3) = Rs. 117.
=> Principal = Rs. (815 – 117) = Rs. 698.
5. In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?
Answer: 2
Solution:Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 – 125) = Rs. 295.
Required percentage = [(295/450)*100]% = [1475/21]%= 70% (approx)
6. Which of the following statements is not correct?
Answer: 2
Solution:(a) Since log_{a}Â a = 1, so log_{10} 10 = 1.
(b) log (2 + 3) = log_{5}Â and log (2 x 3) = log 6 = log 2 + log 3
=> log (2 + 3) log (2 x 3)
(c) Since loga 1 = 0, so log10 1 = 0.
(d) log (1 + 2 + 3) = log 6 = log (1 x 2 x 3) = log 1 + log 2 + log 3.
So, (b) is incorrect.
7.Â If log 27 = 1.431, then the value of log 9 is:
Answer: 3
Solution:log 27 = 1.431
log (3^{3} ) = 1.431
3 log 3 = 1.431
log 3 = 0.477
=> log 9 = log(32 ) = 2 log 3 = (2 x 0.477) = 0.954.
8.Â A vendor bought toffees at 6 for a rupee. How many for a rupee must he sell to gain 20%?
Answer: 3
Solution:C.P. of 6 toffees = Re. 1
S.P. of 6 toffees = 120% of Re. 1 = Rs. 6/5
For Rs. 6/5, toffees sold = 6.
5
For Re. 1, toffees sold = [6 x(5/6) = 5.
9.Â A takes twice as much time as B or thrice as much time as C to finish a piece of work. Working together, they can finish the work in 2 days. B can do the work alone in:
Answer: 2
Solution:Suppose A, B and C take x, x/2, and x/3 days respectively to finish the work.
Then,[(1/x)+(2/x)+(3/x)] = 1/2
=> 6/c = 1/2
=> x = 1
So, B takes (12/2) = 6 days to finish the work.
10.Â Factors of the equation 4x^{2} + 20 x +25 is _______.

4.Â The ratio of the length and the breadth of a rectangle is 4 : 3 and the area of the rectangle is 6912 sq cm. Find the ratio of the breadth and the area of the rectangle?
Answer: 1
Solution:
Let the length and the breadth of the rectangle be 4x cm and 3x respectively.
(4x)(3x) = 6912
12x^{2} = 6912
x^{2} = 576 = 4 * 144 = 2^{2} * 12^{2} (x > 0)
=> x = 2 * 12 = 24
Ratio of the breadth and the areas = 3x : 12x^{2} = 1 : 4x = 1: 96.
5.Â The area of the square formed on the diagonal of a rectangle as its side is 108 1/3 % more than the area of the rectangle. If the perimeter of the rectangle is 28 units, find the difference between the sides of the rectangle?
Answer: 4
Solution:
Let the sides of the rectangle be l and b respectively.
From the given data,
(vl^{2} + b^{2}) = (1 + 108 1/3 %)lb
=> l^{2Â }+ b^{2} = (1 + 325/3 * 1/100)lb
= (1 + 13/12)lb
= 25/12 lb
=> (l2 + b2)/lb = 25/12
12(l2 + b2) = 25lb
Adding 24lb on both sides
12l^{2} + 12b^{2} + 24lb = 49lb
12(l^{2} + b^{2} + 2lb) = 49lb
but 2(l + b) = 28 => l + b = 14
12(l + b)^{2} = 49lb
=> 12(14)^{2} = 49lb
=> lb = 48
Since l + b = 14, l = 8 and b = 6
l – b = 8 – 6 = 2m.
6.Â An order was placed for the supply of a carpet whose breadth was 6 m and length was 1.44 times the breadth. What be the cost of a carpet whose length and breadth are 40% more and 25% more respectively than the first carpet. Given that the ratio of carpet is Rs. 45 per sq m?
Answer: 4
Solution:
Length of the first carpet = (1.44)(6) = 8.64 cm
Area of the second carpet = 8.64(1 + 40/100) 6 (1 + 25/100)
= 51.84(1.4)(5/4) sq m = (12.96)(7) sq m
Cost of the second carpet = (45)(12.96 * 7) = 315 (13 – 0.04) = 4095 – 12.6 = Rs. 4082.40
7.Â The circumferences of two circles are 264 meters and 352 meters. Find the difference between the areas of the larger and the smaller circles.
Answer: 3
Solution:
Let the radii of the smaller and the larger circles be s m and l m respectively.
2?s = 264 and 2?l = 352
s = 264/2? and l = 352/2?
Difference between the areas = ?l^{2} – ?s^{2}
= ?{176^{2}/?^{2} – 1322/?^{2}}
= 176^{2}/? – 132^{2}/?
= (176 – 132)(176 + 132)/?
= (44)(308)/(22/7) = (2)(308)(7) = 4312 sq m
8.Â A cube of side one meter length is cut into small cubes of side 10 cm each. How many such small cubes can be obtained?
Answer: 3
Solution:
Along one edge, the number of small cubes that can be cut
= 100/10 = 10
Along each edge, 10 cubes can be cut. (Along length, breadth, and height). Total number of small cubes that can be cut = 10 * 10 * 10 = 1000
9.Â The length of a rectangle is two – fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 1225 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units?
Answer: 1
Solution:
Given that the area of the square = 1225 sq.units
=> Side of square = v1225 = 35 units
The radius of the circle = side of the square = 35 units Length of the rectangle = 2/5 * 35 = 14 units
Given that breadth = 10 units
Area of the rectangle = lb = 14 * 10 = 140 sq.units
10.Â The ratio of the volumes of two cubes is 729 : 1331. What is the ratio of their total surface areas?
Answer: 1
Solution:
Ratio of the sides = Â³v729 : Â³v1331 = 9 : 11
Ratio of surface areas = 9^{2}Â : 11^{2}Â = 81 : 121
