In the following some of the combinations of operations and an operand
A: means ??3?
B: means ?x3?
C: means ?-3?
D: means ?+3?
E: means ??2?
F: means ?x2?
G: means ?-2?
H: means ?+2?
Expression : 36+12 ? =48
L.H.S. = 36+12 ?
(A) : A followed by F
= $36+12 \div 3 \times 2 = 36+ \frac{12}{3} \times 2$
= $36+8=44$
(B) : A followed by B
= $36+12 \div 3 \times 3 = 36+12=48$ = R.H.S.
=> Ans - (B)
