Select the correct combination of mathematical signs that can sequentially replace ‘A’ and balance the following equation.
28 A 14 A 12 A 6 A 4 A 3 A 4
We need to balance the equation with the correct sequence of operations:
Given 28 A 14 A 12 A 6 A 4 A 3 A 4
Testing each option:
(b) 28-14+12÷6=4×3+4
Solving:
28-14=14
12÷6=2
LHS- 14 + 2 = 16
4×3=12
RHS- 12+4=16
LHS = RHS
So, option (b) fits.
