Correct option is B
Given:
P' stands for 'x'
'Q' stands for '÷',
'R' stands for '-'
'S' stands for '+',
Let's check all the options:
Option (a): (160 R 10) S (30 Q 2) S (16 Q 4) R 45
(160 - 10) + (30 ÷ 2) + (16 ÷ 4) - 45
? = (160 - 10) + 15 + 4 - 45
? = 150 + 15 + 4 - 45
? = 169 - 45
124 ≠ 57
It is incorrect.
Option (b): (160 Q 10) S (30 P 2) R (16 P4) S 45
(160 ÷ 10) + (30 × 2) - (16 × 4) + 45
16 + 60 - (16 × 4) + 45
16 + 60 - 64 + 45
16 + 60 + 45 - 64
121 - 64
57 = 57
we get the resultant of which of the following would be 57 in the option b
Thus, the correct option is (b).
