which number completes the puzzle ? Answer : 29 In each diagram multiply top two values and add their sum to give the bottom value. In first rectangle, (6 * 4 ) + (6 + 4) = 34 In second rectangle, ( 8 * 5 ) + (8 + 5) = 53 Similarly, in last rectangle, (9 * 2) + (9 + 2) = 29 Find missing number in this rectangle filled with numbers. Answer : 6 Find the difference of first two numbers in each row and double it to get third number in that row. 11-2 = 9*2 = 18 5-2 = 3*2 = 6 12-5 = 7*2 = 14 So, answer is 6. All three triangles are interconnected. Find the answer by deriving a relation between them. Answer : 10 Difference of numbers in first two pentagons is in third pentagon at same location. difference of 2,5 = 3 4,5 = 1 7,9 = 2 6,11 = 5 1,10 = 9 ind the missing number in last rectangle with help of other three rectangles. Bottom right rectangle contain result of sum of numbers in first three rectangles at respective positions. 6+3+3...
