Question

If the symbol × denotes the addition of twice the first no. to three times the second,i.e., - What do 4×5 = 0 × 20 mean?

Answer 1

By observation, 4 and 0 are the first numbers and 5 and 20 are the second numbers.

Now,

LHS:

(2*4)+(3*5)

=8+15

=23

RHS:

(2*0)+(3*20)

=0+60

=60

This means that the above given equation is an incorrect equation.
