Explanation:
A rectangular field is 3.2 yards long. A fence marking the boundary is 11.2 yards in length. What is the area of the field in square yards? Correct Answer 7.68 Let, length = a = 3.2 yards and width = b Now, 2 (a + b) = 11.2 a + b = 5.6 b = 5.6 - a b = 5.6 - 3.2 b = 2.4 ab = 3.2×2.4 = 7.68

Explanation:
Akash bought two varieties of rice, costing Tk. 50/kg each, and Tk. 60/kg each, and mixed them in some ratio. Then he sold the mixture at Tk. 70/kg. making a profit of 20%. What was the ratio of the mixture? Correct Answer 1 : 5 Let, he bought x kg at 50/kg rate y kg at 60/kg rate So, the cost price = 50x + 60y and sell price = 70 ( x + y) Now, the profit was 20% if cost price is 100 selling is 120 tk if cost price (50x + 60y) selling is 120( 50x + 60y)/100 120(50x + 60y)/100 = 70(x + y) 60x + 72y = 70x + 70y 2y = 10x 5x = y x/y = 1/5 x : y = 1 : 5
A survey of n people in the town A found that 50% of them prefer Brand X. Another survey of 100 people in the town B found that 60% prefer Brand X. In total, 55% of all the people surveyed together prefer Brand X. What is the total number of people surveyed?
Correct Answer:
D: 200
Explanation:
A survey of n people in the town A found that 50% of them prefer Brand X. Another survey of 100 people in the town B found that 60% prefer Brand X. In total, 55% of all the people surveyed together prefer Brand X. What is the total number of people surveyed? Correct Answer 200 Total = n + 100 Now, total × 55% = n × 50% + 100× 60% ( n + 100) ×.55 = . 50n + 60 .55n + 55 = .50n + 60 .05n = 5 n = 5/.05 = 100 Total = n + 100 = 100 + 100 = 200

Explanation:
In a class, 120 students are male and 100 students are female. 25% of the male students and 20% of the female students are engineering students. 20% of the male engineering students and 25% of the female engineering students passed the final exam. What percentage of engineering students passed the exam? Correct Answer 22% Eng. male = 120×.25 = 30 Eng.female = 100×.20 = 20 Total eng. student = 30 + 20 = 50 Eng.male passed = 30×.20 = 6 Eng female passed = 20×.25 = 5 So, percentage passed = (6 + 5)/50×100% = 22%
The length, width, and depth of a rectangular box are 6 feet, 5 feet, and 7 feet, respectively, A pipe supplies water at a rate of 6 cubic feet per minute. How much time, in minutes, would it take for the pipe to fill a conical box whose volume is three times the volume of the rectangular box?
Correct Answer:
A: 105
Explanation:
The length, width, and depth of a rectangular box are 6 feet, 5 feet, and 7 feet, respectively, A pipe supplies water at a rate of 6 cubic feet per minute. How much time, in minutes, would it take for the pipe to fill a conical box whose volume is three times the volume of the rectangular box? Correct Answer 105 Volume of the box = 6×5×7 So, there time the volume = 3×6×5×7 6 cubic feet filled in 1 minutes So, 3×6×5×7 in 1 minutes = (6×5×7×3)/6 = 105 minutes
