Q4 of 29 Page 1

If a * b denotes the larger of ‘a’ and ‘b’ and if ab = (a*b) + 3, then write the value of (5)(10), where * and are binary operations.

Given: a*b denotes the larger of ‘a’ and ‘b’ and ab = (a * b) + 3

To Find: (5)(10),

So,

510 = (5 * 10) + 3

(5*10 = 10, as 10 is larger than 5)

5∘10 = 10 + 3 

5∘10 = 13.

Hence,

(5)(10) = 13.
