Question

18 is related to 80 following a certain logic. Following the same logic, 23 is related to 100. To which ofthe following is 36 related, following the same logic?(NOTE: Operations should be performed on the whole numbers, without breaking down the numbersinto its constituent digits. E.g. 13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1and 3 is not allowed)

• A. 138
• B. 144
• C. 152
• D. 142

Answer 1

Answer:

C. 152

Observe the pattern:

$18 \rightarrow 80$
$18 \times 5 - 10 = 90 - 10 = 80$
$23 \rightarrow 100$
$23 \times 5 - 15 = 115 - 15 = 100$
A simpler consistent relation is:

Check:

• $(5 \times 18 - 10 = 80)$

• $(5 \times 23 - 15 = 100) (\text{slight mismatch})$

Another exact pattern fitting both is:

$18 \rightarrow 4(18)+8 = 80$
$23 \rightarrow 4(23)+8 = 100$

So rule is:

Now for 36:

$4(36)+8 = 144+8 = 152$

Answer: 152
