Answer 1

Q2. Use the numbers 1, 2, 3, 4, 5, 6, 7, 8 and 9 to satisfy the given equations.

Solution & Explanation

1 + 7 = 8, 9 - 5 = 4, 6 = 3 x 2

Hint : Because in the Last column there is a multiplication operation then it has to be less than 10 and cannot consist 1 because any number multiply by 1 will give the number itself . hence The cases will be 2 x 3 and 2 x 4 . And 3 & 4 cannot be placed in the right hand corner cell , because 2 will be used to drive it . hence the right hand bottom cell has to be 2 .
