balancing the equations Detailed Explanation And More Example

Answer: (a)

From option (a),

17 - 3 x 6 = 45

By interchanging the signs, from the options. We get,

⇒ 17 x 3 - 6 = 45 (using VBODMAS rule)

⇒  51- 6 = 45

⇒  45 = 45

LHS = RHS

∴ So, option (a) is correct.

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.

Answer: (b)

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.

Answer: (c)

From option (c).

24 = 34 ÷ 2 - 5+ 12

⇒ 24 = 17 - 5+12

⇒ 24 = 29 -5

⇒ 24 = 24

Answer: (c)

From option (c),

8 * 8 * 1 * 7 = 8

⇒  8 ÷ 8 x 1+7=8

⇒ 8= 8

Answer: (b)

$√{100} + √{16} = √{225} - √{1}$

10+ 4 = 15 -1

⇒ 14 = 14
