Which of the following letter-number clusters will replace IUP -1 MRN -3 ? ULJ -27 YIH -81

Step 1: Numbers का pattern देखें

Numbers हैं:
-1, -3, ?, -27, -81

यह एक pattern follow कर रहा है:

-1 × 3 = -3
-3 × 3 = -9
-9 × 3 = -27
-27 × 3 = -81

👉 इसलिए missing number = -9

Step 2: Letters का pattern देखें

1st letters:

I → M → ? → U → Y
हर बार +4 का jump:

• I(9) +4 = M(13)
• M(13) +4 = Q(17)
• Q(17) +4 = U(21)
• U(21) +4 = Y(25)

👉 Missing first letter = Q

2nd letters:

U → R → ? → L → I
हर बार -3:

• U(21) -3 = R(18)
• R(18) -3 = O(15)
• O(15) -3 = L(12)
• L(12) -3 = I(9)

👉 Missing second letter = O

3rd letters:

P → N → ? → J → H
हर बार -2:

• P(16) -2 = N(14)
• N(14) -2 = L(12)
• L(12) -2 = J(10)
• J(10) -2 = H(8)

👉 Missing third letter = L

Final Answer:

QOL -9

 सही विकल्प: 3. QOL -9
