Which two signs should be interchanged to make the below equation mathematically correct?

56 - 14 + 42 ÷ 5 × 10 = 63

  1. AOption (a)

    ÷, +

  2. BOption (b)

    ÷, -

  3. COption (c)

    ×, ÷

  4. DOption (d)

    ×, +

View answer & explanation

Correct answer

Answer: (c)C.

×, ÷

Why this answer is correct

  1. ÷, +

Given equation: 56 - 14 + 42 ÷ 5 × 10 = 63

After interchanging the signs, we get:

L.H.S = 56 - 14 ÷ 42 + 5 × 10

= 56 – 0.33 + 50

= 106 – 0.33

= 105.67 ≠ R.H.S

  1. ÷, -

Given equation: 56 - 14 + 42 ÷ 5 × 10 = 63

After interchanging the signs, we get:

L.H.S = 56 ÷ 14 + 42 - 5 × 10

= 4 + 42 – 50

= 46 – 50

= -4 ≠ R.H.S

3) ×, ÷

Given equation: 56 - 14 + 42 ÷ 5 × 10 = 63

After interchanging the signs, we get:

L.H.S = 56 - 14 + 42 × 5 ÷ 10

= 56 – 14 + 21

= 77 – 14

= 63 = R.H.S

  1. ×, +

Given equation: 56 - 14 + 42 ÷ 5 × 10 = 63

After interchanging the signs, we get:

L.H.S = 56 - 14 × 42 ÷ 5 + 10

= 56 – 117.6 + 10

= 66 – 117.6

= -51.6

Hence, ‘×, ÷’ is the correct answer.

  2. BOption (b)

    96 kg

  3. COption (c)

    76 kg

  4. DOption (d)

    69 kg

View answer & explanation

Correct answer

Answer: (b)B.

96 kg

Why this answer is correct

Let the weight of R be 'a' Kg.

If P weighs is 3 kg more than Q who is thrice as heavy as R.

According to question:

Q = 3a

And P = 3a + 3

If the total weights of P, Q and R be 227 kg.

P + Q + R = 227 Kg

Putting the value of P, Q and R in the above equation, we get:

3a + 3 + 3a + a = 227

⇒ 7a + 3 = 227

⇒ 7a = 227 - 3

⇒ 7a = 224

⇒ a = 224/7

⇒ a = 32

so, weight of R is 32 Kg.

Weight of Q = 3a

= 3 × 32 Kg

= 96 Kg

Therefore, weight of Q is 96 Kg.

Hence, ‘96 Kg’ is the correct answer.

Question 160

    43

View answer & explanation

Correct answer

Answer: (c)C.

55

Why this answer is correct

The logic is:

13 ∶ 143 → 13 : 13 × 11

Similarly,

5 ∶ ? → 5 : 5 × 11

⇒ ? = 55

Hence, ‘55’ is the correct answer.
