Question : Direction: In this question, some equations are solved on the basis of a certain system. Find out the correct alternative for the unsolved equation on that basis.
4 x 5 x 8 =584
7 x 3 x 9 = 397
9 x 7 x 3 = ?
Option 1: 397
Option 2: 793
Option 3: 973
Option 4: 739
Correct Answer: 739
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.
⇒ 4 x 5 x 8 =584
⇒ 7 x 3 x 9 = 397
Following the same pattern in the unsolved equation, we get –
⇒ 9 x 7 x 3 = 739
Hence, option fourth is correct.
