Q.1 The product of two numbers is 300 and their H.C.F. is 5. Then their L.C.M. is
Check Solution
Ans: C
We know that product of two numbers = H.C.F. * L.C.M. Therefore, L.C.M. = Product / H.C.F. = 300 / 5 = 60
Q.2 The perimeters of a square and a regular hexagon are equal. The ratio of the area of the square to the area of the hexagon is:
Check Solution
Ans: D
Let the side of the square be ‘s’. Then the perimeter of the square is 4s. The perimeter of the hexagon is also 4s, so each side of the hexagon is 4s/6 = 2s/3. Area of square = s^2. Area of hexagon = (3√3/2) * (side)^2 = (3√3/2) * (2s/3)^2 = (3√3/2) * (4s^2/9) = (2√3/3)s^2. Ratio of areas = s^2 / ((2√3/3)s^2) = 3/2√3 = √3/2
Q.3 The curved surface area of a cylinder is 440 square cm. If the radius of the base is 7 cm, then the height of the cylinder is
Check Solution
Ans: B
Curved Surface Area of cylinder = 2πrh, 440 = 2 * (22/7) * 7 * h, h = 10 cm
Q.4 A solid sphere of radius R is melted and recast into a solid cone of height R. The radius of the cone is:
Check Solution
Ans: D
Volume of sphere = (4/3)πR^3. Volume of cone = (1/3)πr^2h = (1/3)πr^2R. Equating volumes: (4/3)πR^3 = (1/3)πr^2R. 4R^2 = r^2. r = R*2^(1/2). However, it seems there is a mistake in the choices as the answer must be R*4^(1/3)
Q.5 P and Q together can finish a task in 10 hours, Q and R can do it in 12 hours, and P and R can complete it in 15 hours. How long will it take for P, Q, and R to finish the same task working together?
Check Solution
Ans: A
Let the work done by P, Q and R in 1 hour be p, q and r respectively. Given: p + q = 1/10, q + r = 1/12, p + r = 1/15 Adding the three equations: 2(p + q + r) = 1/10 + 1/12 + 1/15 = (6+5+4)/60 = 15/60 = 1/4 Therefore, p + q + r = 1/8 So, P, Q and R together can finish the work in 8 hours.
Q.6 X and Y together can finish a task in 12 days. They work together for 8 days, then X quits. If Y finishes the remaining task in 6 more days, then X alone could have finished the entire task in:
Check Solution
Ans: D
Let the total work be the LCM of 12 and 18 which is 36 units. (X+Y)’s 1 day work = 36/12 = 3 units (X+Y)’s 8 days work = 3 * 8 = 24 units Remaining work = 36 – 24 = 12 units Y’s 6 days work = 12 units Y’s 1 day work = 12/6 = 2 units X’s 1 day work = 3 – 2 = 1 unit X alone could finish the task in = 36/1 = 36 days
Q.7 X is 25% more efficient than Y. If Y takes 20 days to complete a work, then how many days will X take to complete the same work?
Check Solution
Ans: B
Let Y’s efficiency be 100. Then X’s efficiency is 125. Y takes 20 days, so the total work is 100 * 20 = 2000 units. X’s time = Total work/ X’s efficiency = 2000/125 = 16 days.
Q.8 A rational number between 1/5 and 1/3 is
Check Solution
Ans: C
We need to find a number that is greater than 1/5 and less than 1/3. Convert to decimals: 1/5 = 0.2, 1/3 = 0.333… 1/2 = 0.5, 1/10 = 0.1, 1/4 = 0.25, 2/15 = 0.133… Only 1/4 (0.25) falls within the range.
Q.9 The number of ways in which the letters of the word SUCCESS can be arranged
Check Solution
Ans: C
The word SUCCESS has 7 letters. The letter S appears 3 times, and the letter C appears 2 times. Therefore, the number of arrangements is 7! / (3! * 2!) = 5040 / (6 * 2) = 420.
Q.10 A sum of Rs. 660 is divided among A, B and C such that B receives twice as much as A and C receives thrice as much as B. The ratio of their shares is
Check Solution
Ans: B
Let A’s share be x. B’s share is 2x. C’s share is 3 * 2x = 6x. x + 2x + 6x = 660, 9x = 660, x = 660/9. A’s share = 660/9, B’s share = 1320/9, C’s share = 3960/9. The ratio is (660/9) : (1320/9) : (3960/9) which simplifies to 1 : 2 : 6.
