Answer: Option A

Explanation:

মনেকরি,
টিমের সদস্যদের বয়সের গড় x বছর
.: অধিনায়ক ও উইকেট রক্ষক বাদে অন্য 9
জনের গড় = (x - 1) বছর
দেওয়া আছে,
অধিনায়কের বয়স = 26 বছর
.:. উইকেট রক্ষকের বয়স = 26 + 3 = 29 বছর
প্রশ্নমতে,
9 (x - 1) + 26 + 29 = 11x ⇒ 9 x - 9 + 26 + 29 = 11x
⇒ x = 23

Answer: Option D

Explanation:

মনেকরি, আয়তক্ষেত্রের উচ্চতা = h
.:. আয়তক্ষেত্রের ভূমি = 3h
তাহলে, পরিসীমা = 2(h + 3h)
= 2 x 4h
= 8h

প্রশ্নমতে,
8h = 64
⇒ h = 8
.:. আয়তক্ষেত্রের উচ্চতা = ৪
এবং ভূমি = 3 × 8 = 24
তাহলে আয়তক্ষেত্রের ক্ষেত্রফল = ভূমি উচ্চতা
= 24 x 8 = 192

Answer: Option B

Explanation:

Let's denote the present ages of the husband, wife, and child as H, W, and C, respectively.

According to the given information:

Four years ago, the average age of the husband, wife, and child was 27 years. So, (H - 4 + W - 4 + C - 4) / 3 = 27.

Five years ago, the average age of the wife and child was 20 years. So, (W - 5 + C - 5) / 2 = 20.

We can simplify these equations:

1. (H + W + C - 12) / 3 = 27.

2. (W + C - 10) / 2 = 20.

Now, let's solve this system of equations:

From equation 2, we can express W + C as 2 * 20 + 10 = 50.

Substitute this value into equation 1:

(H + 50 - 12) / 3 = 27.

H + 38 = 81.

H = 81 - 38.

H = 43.

So, the present age of the husband is 43 years.

A. 22 years
B. 30 years
C. 40 years
D. 32 years

Answer: Option D

Explanation:

Total age of 10 students = 20×10 = 200
Total age of 12students = (20 + 2)12 = 264
∴ age of 2 new students = 264 - 200 = 64
average = 64/2 = 32
