ব্যাখ্যা (Explanation)

Let their ages 10 years ago is x, 2x and 3x years. 10 + 2x + 10 + 3x + 10 = 90 hence x= 10 B’s present age = (2x + 10) =30 years

If n is even, which of the following cannot be odd?

ক) n+1 খ) 3n+1 গ) n^2-1 ঘ) 2(n+3)

The average of a and b is And the average of b and c is 35, then (a - c) = ?

A ferry can carry 24 buses or 36 cars at a time. If there are 18 buses on the ferry,how many cars can be loaded onto it?

ক) 6 খ) 8 গ) 9 ঘ) 12

Bony takes 2 hours to wash 500 dishes, and Farah takes 3 hours to wash 450 dishes. How long will they take working together to wash 1000 dishes?

ক) 1 hour খ) 2 hours গ) 2.5 hours ঘ) 3 hours

ব্যাখ্যা (Explanation)

Ben washes 500 dishes / 2 hours = 250 dishes / 1 hour.

Frank washes 450 dishes / 3 hours = 150 dishes / 1 hour.

dishes that Frank washes in x hours + dishes that Ben washes in x hours = 1000 dishes

250x + 150x = 1000

400x = 1000

x = 2.5

ব্যাখ্যা (Explanation)

total=taxable cost+tax free cost + tax so, taxable cost=(25-x-0.3)

now, taxable cost* rate of tax(%)=tax so (25-x-0.3)*6/100=0.3

so,tax free price = ( 20-.3) =17.70 tk

The ratio of salaries of A, B and C is 1:2: The salaries of B and C together are Tk. 6, By what percentage is the salary of C more than that of A.

ক) 100% খ) 200% গ) 300% ঘ) 600%

ব্যাখ্যা (Explanation)

Let the salaries of A, B, C be x, 2x and 3x respectively. Then,2x + 3x = 6000 => x = 1200. A's salary = Rs. 1200, B's salary = Rs. 2400, and Cs salary Rs. 3600. Excess of C's salary over A's=[ (2400 /1200) x 100] = 200%.

1/4 of Ram's money is equal to 1/6 of Shyam's money. If both together have Tk. 600, the difference between their amount is-

ক) 50 খ) 120 গ) 240 ঘ) 360

ব্যাখ্যা (Explanation)

Here, 1/4 of Ram’s money = 1/6 of Shyam’s money = Tk. x Therefore, Ram’s money = Tk. 4x and Shyam’s money = Tk. 6x Therefore, R : S = 4x : 6x = 4 : 6 = 2 : 3. In the ratio we get, Ram's money = Tk.240 & Shyam's money = Tk. 360. Then the difference = Tk. (360 - 240) or, Tk.120
