A. ৯১২
B. ৯২১
C. ৯৩০
D. ১০৯২
E. ১২৯০

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

To find the largest 3-digit number using the digits x, y, and z (where x + y + z = 12), you want to maximize the leftmost digit to make the number as large as possible.

The largest possible leftmost digit is 9, as it's the largest single-digit number. To form the largest 3-digit number, you should place 9 as the leftmost digit. Now, you need to arrange the remaining digits (x and y) in the rightmost positions to maximize the number further.

To maximize the number, you should place the next largest digit (8, if available) in the hundreds place and the remaining digit in the tens place. If 8 is not available, use the next largest available digit.

So, if we place 9 in the hundreds place, and if x and y are the remaining digits, the largest number will be 9xy.

Now, we need to find the combination of x and y that adds up to 12. The only combination that satisfies this is x = 3 and y = 0.

So, the largest 3-digit number using the digits x, y, and z (where x + y + z = 12) is 930.

Therefore, the correct answer is 930.

So, the price of rice in the year 1995 = 100 + 10 = Tk. 110
The price of rice in the year 1996 = 110 - 5.5 = 104.5

Answer: Option C

Explanation:

First,we know that all the angles in a triangle add up to 180 degrees.

Each triangle has 3 angles. Thus, we have the sum of three angles as shown:

180 = A + B + C

where we have angles A, B, and C. In our right triangle, one angle is 30 degree and we'll call that angle A. The other known angle is 90 degrees and we'll call this angle B. Thus, we have

180 = 30 + 90 + C

Simplify and solve for C.

180 = 120 + C
