(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.Oper\rations on 13 such as adding /subtracting/multiplying to 13 can be performed.Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.?

• A. 101
• B. 105
• C. 107
• D. 103

Answer 1

Answer:

D. 103

Let’s find the pattern:

Given:

• 14 → 68

• 17 → 83

  Observe relation

Try:
$14 \times 5 - 2 = 70 - 2 = 68$
$17 \times 5 - 2 = 85 - 2 = 83$

So pattern is:
$\text{Number} \times 5 - 2$

Apply to 21

$21 \times 5 - 2 = 105 - 2 = 103$

Final Answer: 103
