5 Answers ID : in-4-logical-reasoning [5] (1) 158,164 Lets observe the boxes where numbers 162 and 165 are written 162 is at 12 th position 165 is at 15 th position Dif f erence in their position = = 3, Dif f erence in numbers = = 3 From above dif f erences we can inf er that each part on this line represent 1 Step 4 Theref ore number at f irst position should be, = (12-1) = 151 Step 5 First missing box is at 8 th position Number at 8 th position = (8-1) = 158 Step 6 Second missing box is at 14 th position Number at 14 th position = (14-1) = 164 (2) 10 Lets f ind sum of top-lef t to bottom-right diagonal where all terms are known, = 32 Now lets f ind sum of all available terms in top-right to bottom-lef t diagonal, = 22 Since it is given that sum of both diagonals are same, missing terms must be equal to dif f erent of above two sum. Theref ore missing term = = 10

6 (3) c. Copier 2 ID : in-4-logical-reasoning [6] (4) c. On noticing sequence of images, and we can see, - 1 st picture is vertical rectangle - 2 nd picture is triangle - 3 rd picture is horizontal rectangle - 4 th picture is f lipped triangle - 5 th picture is vertical rectangle - 6 th picture is triangle - 7 th picture is horizontal rectangle So we can see that every alternate image is a rectangle, and it is rotated f rom horizontal to vertical and vice-versa Similarly another alternate image is a triangle, which is f lipped horizontally Step 4 Since image bef ore last image is a vertical rectangle next image should be horizontal rectangle (5) d. 5 If you observe this series, you will notice f ollowing, - First term is 1 - Next 2 terms (2 nd to 3 rd terms) are 2 - Next 3 terms (4 th to 6 th terms) are 3 - Next 4 terms (7 th to 10 th terms) are 4 Similarly we can f ind f ollowing missing terms as f ollowing - Next 5 terms (11 th to 15 th terms) will be 5 - Next 6 terms (16 th to 21 st terms) will be 6 - and so on... Now we can see that 12 th term will be 5. (6) c. 1 Kg.

7 (7) d. In 3 weeks Matthew ate f ewer candies than Lovleen ID : in-4-logical-reasoning [7] (8) b. North-East In this picture Z shows zoo. Now lets draw a line in West direction to A (airport) as shown below Now lets another line of same length in North direction f rom Z (zoo) to B (bank) as shown below, From above picture we can show that bank is in North-East direction f rom airport (9) c. 16 f eet (10) a. 13 Total number of books read by Ridhima, Pradip, Harsh and Sita, = = 72 It is given that Sachin reads 5 books less than 1 4 of 72. Theref ore number of books read by Sachin, = = 18-5 = 13 books

8 (11) 27 ID : in-4-logical-reasoning [8] If you compare numbers in f irst two pictures, you will observe that numbers are multiplied by 2 and then 1 is added, = = = 17 Similarly, if you compare numbers in last two pictures, you will observe that here also numbers are multiplied by 2 and then 1 is added, = = = 21 Theref ore we can f ind missing number by multiplying 2 to 13, and then by adding 1, Missing number = = 27 (12) 3 6 Symmetric letter are : I V W Asymmetric letter are : G P S Total symmetric and asymmetric letter are : 6 Step 4 Now the f raction of symmetric (either horizontal or vertical) letters on the cube = 3 6

9 (13) 6 ID : in-4-logical-reasoning [9] The f irst statement tells us that one box contains 4 apples. Theref ore, 3 boxs = 3 4 = 12 apples. T he second statement tells us that one jar contains 2 strawberries. Step 4 Theref ore, 3 jars = 3 2 = 6 strawberries. Step 5 Thus, the dif f erence between the number of apples and strawberries = 12-6 = 6 (14) (15) The x-axis and y-axis of the bar chart shows the name of the f ruits and the amount of f ruits in a shop respectively. If you look at the bar chart caref ully, you will notice that the number of pears in a shop = 70, the number of peaches in a shop = 20 Now the dif f erence of number of pears and peaches in a shop = = 50, theref ore we can say that there are 50 more pears than peaches.
