Answer explanations:

1.b 

⇒multiply 6,5 and 4 and you will receive 120 as a result.In same way multiply  8,5 and 8 in order to achieve 320 as result.

2.a

⇒subtract the top number from the sum of remaining two numbers i.e.10-(7+1)=2 as 26-(11+5)=10

3.b

half the first number and double the second number and sum them to 

get answers.For ex.6/2 +11*2=25 and  12/2 + 5*2 = 16.

4.d

double the second number and add it to the first number to get the answers.For ex.13+7*2=27

5.d

start form the bottom and multiply first number by 2 to get second number,multiply 2nd number by 3 to get the third number and so on.i.e. 16*2=32, 32*3=96 , 96*4=384

6.c

multiply 1st and 3rd number and add it with 2nd number to get the answers. For ex. 5*5+6=31

7.c

the square root of the last number equals to the sum of all three numbers. For ex. √169= 5+5+3

8.a

add 2nd and 3rd number in column and multiply it with first  number to get the answers.  i.e. (4+1)*9=45

9.a

subtract third number in a row with first number and multiply it with 11 to get the answers.For ex. (42-38)*11=44

10.d

multiply 1st and second number in column and add it with first number as 7*14+7=105
