Answer 1

ANSWER.

• Total points he scored = 0.

SOLUTION.

Here, one scores point 2 if even number is rolled or else -3 if odd number is rolled.

Here,

→ Rajesh rolled 6 even numbers.

→ Points scored here = 6 × 2 = 12

Wait!

→ He also rolled 4 even numbers.

→ Points scored here = 4 × (-3) = -12

Therefore, the total points he scored will be,

= 6 × 2 + 4 × (-3)

= 12 - 12

= 0 (Answer)

Answer 2

6 × 2 - 4 × 3 = 0

Hope it's clear to you...
