Question : Direction: In this question, some equations are solved on the basis of a certain system. On the same basis find out the corrective alternative for the unsolved equation.
1 x 2 x 3 = 231
3 x 4 x 5 = 453
5 x 6 x 7 = ?
Option 1: 657
Option 2: 675
Option 3: 756
Option 4: 765
Correct Answer: 675
Solution : Here, the given equations follows a pattern in which the first number, the middle number and the last number in LHS becomes the units place digit , the hundreds place digit and the tens place digit in the answer part in RHS respectively.
⇒ 1 x 2 x 3 = 231
⇒ 3 x 4 x 5 = 453
Following the same pattern in the unsolved equation , we get –
⇒ 5 x 6 x 7 = 675
Hence, second option is correct.
