The area of a field is 680 square feet . If the cost of fencing is Tk 50 per foot , then how much will it cost to fence the field? Correct Answer Tk 8800 Let, length = 68 m and width = 10m So, area = 10×68 = 680 Cost of fencing = ( 10×2×50) + ( 68×2×50) = Tk.7800 ( correct answer)

Explanation:

There are tow examinations rooms A and B. If 10 students are sent from A to B, then the number of students in each room is the same . If 20 candidates are sent from B to A, then the number of students in a is double the number of students in B. what is the number of students in room A? Correct Answer 100 Let, the no of students in room A and B be x and y Then, x - 10 = y + 10 and, x + 20 = 2 ( y - 20) Solving, x = 100, y = 80

Explanation:

Rafia ran from her house to schoolat an average speed of 6 miles per hour and returned along the same route at an average speed of 4 miles per hour . If it took her one hour in total to run to the school and come back, how many minutes did it take her to run from her house to school? Correct Answer 16 Let, Distance = D we know that , T = D/s Here, T = time, D = ddistance, S = speed According to question, D/6 + D/4 = 1 (2D + 3D) /12 = 1 D = 12/5 6 mile go 1 hours or 60 minutes 1 mile go 60/6 minutes 12/5 mile go ( 60×12)/ ( 6×5) = 24 minutes ( correct answer)

Explanation:

A school has raised 75% of the amount it needs for a new building by receiving an average donation of Tk 60 from the people already solicited. The people already solicited represent 60% of the people the college will ask for donations If the college is to raise exactly the amount needed for the new building , how much must the remaining people donate per person? . Correct Answer Tk 30 Let Total people = 100 60% people of total people = 60 They donate amount = 60×60 = 3600 Remaining people = 100 - 60 = 40 And remaining amount = ( 3600×100) 75 - 3600 = 4800 - 3600 = 1200 They donate per person = 1200/40 = 30Tk.

Explanation:

At 10 a.m. two trains started travelling toward each other from stations 287 miles apart. They passed each other at 1:30 pm the same day. They average speed of the faster train exceeded the average speed of the slower train by 6 miles per hour. which of the following represents the speed of the faster train, in miles per hour? Correct Answer 44 Let the average speed of slower and faster trains be S and (S + 6) miles/hr respectively. Time taken = 10 am to 1:30 pm = 3.5 hr Distance travelled by slower train = 3.5S Distance travelled by faster train = 3.5(S + 6) Now,  3.5S + 3.5(S + 6) = 287 or, 3.5S + 3.5S + 21 = 287 or, 7S = 287 - 21 or, 7S = 266 or, S = 266/7 = 38 miles/hr So, speed of the faster train, S + 6 = 38 + 6 =  44 miles/hr

Correct Answer 4% the value of XYZ Company stock drops from tk. 25 per share to tk. 21 per share = 25 - 21 = 4 tkThe percentage decrease = Change*100/base year value = 4*100/25 = 16% (ans)

Explanation:

Seats for Mathematics, Physics and Biology in a university are in the ratio 5: 7: 8, There is a proposal to increase these seats by 40% , 50% and 75% respectively. what will be ratio of increased seats? Correct Answer 2: 3: 4 Let, the number of seats for Math, physics, and biology, be 5x, 7x and 8x respectively Number of increased seats are ( 140% of 5x). (150% of 7x) ( 175% of 8x) = (140/100×5x) , ( 150/100×7x), ( 175/100×8x) 7x, 21x/2, 14x The required ratio = 7x : 21x/2 : 14x = 14x : 21x : 28x = 2 : 3 : 4

Explanation:

Tom, Dick and Harry went for lunch to a restaurant. Tom had Tk. 100 with him. Dick had Tk. 60 and Harry had Tk . 40. They got a bill for Tk. 104 and decided to give a tip of Tk. 16 . They further decided to share the total expenses in the ratio of the amounts of money each carried . They amount of money which Tompaid more than what Harry paid is Tk.--- Correct Answer 36 Total pay = 104 + 16 = 120 TK Now,  Tom : Dick : Harry = 100 : 60 : 40 = 5 : 3 : 2 So, Tom paid = 5 / (5 + 3 + 2) × 120 = 60 TK Harry paid = 2 / (5 + 3 + 2) × 120 = 24 TK Tom more paid than Harry = 60 - 24 = 36 TK

Explanation:

If a : b = 3 : 5 and a : c = 5 : 7, what is the value of b : c? Correct Answer 25 : 21 Here,  a : b = 3 : 5 = (3×5) : (5×5) = 15 : 25 Again,  b : c = 5 : 7 = (5×3) : ( 7×3) = 15 : 21 So,  a : b : c = 15 : 25 : 21 Therefore,  b : c = 25 : 21
