If 11×11 = 4, 22×22 = 16, then 33×33 = ?

Show answer & explanation

Correct answer: A

Explanation

11×11=121

Sum of digits = 1+2+1=4

But 22×22=484

Sum of digits = 4+8+4=16

33×33=1089

Sum of digits = 1+0+8+9=18

So if the coding rule is really "sum of the digits of the product," then:

33×33=1089

1+0+8+9=18

Hence, the answer is 18 (option 1).
