If “P” denotes “multiplied by”, “Q” denotes “subtracted from”, “S” denotes “added to” and “R” denotes “divided by”, then which of the following equation must be true ?

Option (1)

7 S 56 P 2 R 28 = 11

$\Rightarrow 7+56 \times 2 \div 28=11$

$\Rightarrow 7+56 \times \frac{2}{28}=11$

$\Rightarrow 7+4=11$

Option (2)

36 R 6 P 2 S 4 = 19

$\Rightarrow 36 \div 6 \times 2+4=19$

$\Rightarrow 6 \times 2+4 \neq 19$

Option (3)

64 R 8 P 3 S 6 = 72

$\Rightarrow 64 \div 8 \times 3+6=72$

$\Rightarrow 8 \times 3+6=72$

$\Rightarrow 24+6 \neq 72$

Option (4)

36 R 9 S 4 P 2 = 14

$\Rightarrow 36 \div 9+4 \times 2=14$

$\Rightarrow 4+8 \neq 14$
