(A) 9

(B) 20

(C) 21

(D) 39

### Explanation:-

###### If a book has 50 pages, means in that book half means [50/2 = 25] odd number pages and half means [50/2 = 25] even numbered pages.

Mohit crossed 4 odd numbered pages means 25-4 = 21

And 5 even numbered pages means 25-5 = 20

So 20 even numbered pages are not crossed out. Then the correct answer is B.

##### 56, 3 × 8, 29, 2 × 7, 2, 19

(A) 56, 29, 3 × 8, 19, 2 × 7, 2

(B) 56, 2 × 7, 3 × 8, 29, 2, 19

(C) 2, 2 × 7, 19, 3 × 8, 29, 56

(D) 2 × 7, 3 × 8, 29, 2, 19, 56

##### Explanation:-

56, 3 × 8, 29, 2 × 7, 2, 19 ,

56, [3*8 = 24], 29, [2*7 =14], 2, 19

With this equation we got the answer is 56,24,29,14,2,19

Now we have to arrange these from greatest to smallest

So …. 56, 29, 24, 19, 14, 2 means 56, 29, 3 * 8, 19, 2* 7, 2 this means the correct answer is A

(A) 115 + 5

(B) 115 + 25

(C) 115 + 30

(D) 115 + 50

### Explanation:-

if we add …… 31 + 32 + 33 + 34 + 35 = 165, we got 165. , now we have to find the option with 165 as answer.

A option 115+5 = 120 [false]   , B option 115 +25 = 140 also false, C option 115 + 30 = 145 also false D option 115+50 = 165 is the correct answer.
