What should be the correct signs to balance the following equation?
3 + 2 × 1=7
Options:
A . x, + and =
B . +, x and =
C . =, x and +
D . x, = and +
Answer: Option A Answer: (a) Let us check all the options one-by-one. From option (a). 3+2 x 1 = 7 By interchanging the signs, from the options. We get, ⇒ 3 x 2 + 1=7 (using VBODMAS rule) ⇒ 6 + 1 =7 ⇒ 7 = 7 ∴ LHS = RHS As an option (a) gives us a correct answer, there is no need to check the remaining options.
