Question 15

If 4 * 7 * 2 = 361 and 5 * 9 * 1 = 480, then

2 * 1 * 3 = ?

Solution

The pattern followed is that 1 is subtracted from each number and the result is concatenated.

Eg : 4 * 7 * 2 = $$(4-1) (7-1) (2-1) \equiv361$$

and 5 * 9 * 1 = $$(5-1) (9-1) (1-1) \equiv480$$

Similarly, 2 * 1 * 3 = $$(2-1) (1-1) (3-1) \equiv102$$

=> Ans - (D)
