What should be the correct signs to balance the following equation?
Q-11) 6 5 4 = 34
(a)
(b)
(c)
(d)
Let us check all the options one by one.
From option (a),
6 -5 + 4 = 34 (using VBODMAS rule)
⇒ 10 - 5 = 34 ⇒ 5= 34
∴ LHS ≠ RHS
So, option (a) is incorrect.
From option (b),
6 x 5+ 4 = 34 (using VBODMAS rule)
⇒ 30+ 4 = 34 ⇒ 34 = 34
⇒ LHS = RHS
So, option (b) gives us the correct answer and hence, there is no need to check remaining options.
