D. 96

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

অঙ্কদ্বয়ের সমষ্টি = ৮ + ৭ = ১৫
এবং ৮৭ - ৯ = ৭৮
অর্থাৎ ৯ বাদ দিলে ৮৭ স্থান পরিবর্তন করে ৭৮ হয়।
অতএব, অপশন ধরে উত্তর বের করা যায় ৮৭.

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Assuming decimal (base 10) numbers…

For the first digit, we have exactly one choice: 9.

For the second digit we have exactly 8 choices: 0, 1, 2, 4, 5, 7, 8, and whichever of 3/6 is not used in the third digit.

For the third digit, we have exactly two choices: 3 or 6.

For the fourth digit, we have exactly 7 choices: 10 possibilities minus the three used in digits one, two, and three.

For the fifth digit, we have exactly 6 choices: 10 possibilities minus the four used in digits one, two, three, and four.

So the number of our choices is 1 × 8 × 2 × 7 × 6, or 672 five-digit numbers with no digit repeated.

Answer: Option D

Explanation:

To guarantee that one of each type of soda (orange, cream, and cherry) has been chosen, you need to remove enough sodas to ensure that you have at least 1 of each type.

First, remove 10 orange sodas. Now you have 10 orange, 15 cream, and 7 cherry sodas remaining.

Next, remove 15 cream sodas. Now you have 10 orange and 7 cherry sodas remaining.

Finally, remove 1 cherry soda.

At this point, you will have removed a total of 10 (orange) + 15 (cream) + 1 (cherry) = 26 sodas to guarantee that you have at least one of each type.

Answer: Option A

Explanation:

Let's assume Frank scored "x" three-point baskets and "y" two-point baskets. We are given that Frank scored 26 points, and all of his points came from two-point or three-point baskets. We also know that he scored at least one three-point basket. So, we have the following equations: 3x (for the three-point baskets) + 2y (for the two-point baskets) = 26 (total points) x ≥ 1 (at least one three-point basket) We want to find the maximum number of two-point baskets (y) Frank could have scored. To do this, we'll try to maximize "y" while satisfying the given conditions. Let's start by substituting the minimum value for "x" (which is 1) into equation 1: 3(1) + 2y = 26 3 + 2y = 26 Now, subtract 3 from both sides: 2y = 26 - 3 2y = 23 Divide by 2: y = 23 / 2 y = 11.5 Since the number of baskets must be a whole number (you can't have half a basket), we'll round down to the nearest whole number: y = 11 So, Frank could have scored a maximum of 11 two-point baskets.
