Answer 1

The correct option is D $\times$ and $-$

Using Hit and Trial method for solving:

Applying Option A

$59\times 45-15+3÷5\ne 23$

Applying Option B

$59+45\times 15-3÷5=$

$59+675-3÷5\ne 23$

Applying Option C

$59÷45+15-3\times 5\ne 23$

Applying Option D

$59-45+15\times 3÷5=14+3\times 3=14+9=23$

Hence, option 'D' is correct.
