Question: What is the missing number?

Solution: 
n the first column, (9 × 5) - 7 =38.
In the second column, (11 × 9) - 22=77.

So, the answer is 160

Question: How many triangles are there?



Solution:


The simplest triangles are AFB, FEB, EBC, DEC, DFE, and AFD so, 6 triangles.
The triangles are composed of two components: AEB, FBC, DFC, ADE, DBE, and ABD so, 6 triangles
The triangles composed of three components are ADC and ABC so, 2 trangles.
There is only one triangle DBC which is composed of four components.

Thus, there are 6 + 6 + 2 + 1 = 15 triangles in the figure.

Question: What number will replace the '?' mark?
2, 4, 12, 48, 240, ?, 10080

Solution:
২য়, ৩য়, ৪র্থ, ৫ম, ৬ষ্ঠ সংখ্যাকে যথাক্রমে 2, 3, 4, 5, 6, 7 দ্বারা ক্রমান্বয়ে গুণ করা হয়েছে।
2 × 2 = 4
4 × 3 = 12
12 × 4 = 48
48 × 5 = 240
240 × 6 = 1440
1440 × 7 = 10080

Question: If A = A and B = D then what will be equivalent to C?

Solution:
A = A(1 = 1)
B = D(2 = 4)
from the above relation, we get,
1² = 1
2² = 4

As C values 3 in the alphabet rank,
3² = 9
so, C = I

Question: Asha and Disha are cousins. Rakib is Asha's mother's husband. Tanvir is the son of Himejima and the father of Disha. Who is Asha to Himejima?

Question: If Titu is three years older than double the age of Puja and Pavel is 7 years senior to Puja. Tithi is Pavel's wife and 3 years junior to Pavel. What is the age of Tithi if Titu is 57 years old?

Solution: 
As per the question,
Let
Puja's age be x
Titu's age  = 2x + 3
Now
2x + 3 = 57
2x = 57 - 3
2x = 54
x = 27

Pavel = x + 7 = 27 + 7 = 34

Tithi is = 34 - 3 = 31

Question: Apple is producing the iPhone at a cost of 200 dollars and selling it at 600 dollars. In the production of 100 phones, 40 were defective phones. What is the percentage of loss or profit?

Solution: 
100 phones making cost = (100 × 200) = 20000 dollars.
Selling price of 60 phones =  (60 × 600) = 36000 dollars

profit = (36000 - 20000) = 16000

profit percentage = (16000/20000)100%
= 80%

Question: What will come at the place of the question mark?
4, 8, 10, 14, 16, 20,?

Solution:

Question: Kobir walks 10 km towards North. From there he walks 6 km towards South. Then, he walks 3 km towards East. How far and in which direction is he with reference to his starting point?

Solution:

শুরুস্থান A এবং গন্তব্যস্থান D
AC = 10 - 6 = 4 কিমি

AD² = 4² + 3²
AD² = 16 +9
AD² = 25
AD² = 5²
AD = 5

from the series
the first letter of each word is in the opposite direction of X, Y, and Z. So, the letter before X is W

next letter is in the sequence of A, B, C. so the next letter will be D
third letter of the series is also in the opposite direction Q, R, and S . So, the letter before Q is P
